    Ok.

    I looked at all the blazers I could find. 6 in total. Unfortunately, 2 were S10 blazers.
    There was 1 ’87, 2 ‘88’s and a ’90. All 4 had an AC and the small radiator in front of the big one. All 4 also had OD (been told it is called a TH700R4). All also had 10bolt axles and to my disgust all had 3.08 gears. All were on 31’s and all had the same 2H-4H-N-4L pattern in the transfer case. So right now it is all about color and rust.

    Now one of the 88 ones had no rust, but there was some sort of leak in the cabin. Behind the drivers seat the floor was wet. What can this be? I found this very strange to find this in the best looking of all. The owner even showed me that the floor was wet but not rotten. He didn’t know there the leak was also. He was thinking that it was either the seals of the hardtop or a leak in the rail above the door. You know, that gutter. I looked there and there was a strange opening. Just as if the roof was not welded on properly. Can water make it’s way from there to the floor?

    Anyway. It’s going to be one of these blazer, so I think I’m looking for a 12bolt axle. Any tips or does anyone live close enough to maybe do some shipping? Just checking.

    Hi Lana
    Im in Norway and understand there isn't alot to pick from. Water leaks in mine to. I had the front windshield replaced and it took care of most of it. But I still get some water in the drivers seat through the top of the door opening. I took a piece of wire and wedged behind the door gasket and it helped a litle. If the driverseat is left bent foreward the water could leak from the windshield and run down the seats back, but most likely it's in the hard-top joint.

    I have a 88 diesel blazer thats afordable and clean. Are you only looking at gasolin blazers. Do the military have any auctions where maybe NATO would sell some?
    Good luck with whatever you decide. I thought mine was "mint" when I got it, but it still needed some tender love and care to get to where it is today

    Well if you found a rust free 88 blazer in good running condition. That might be the one to pick.The leak is prbabally from a bad seal on the top. Which is a lot easir to repair than rust. A little silicone will do wonders.
    Also by 1988 GM had fixed a lot of the problems that plauged the 700r4 tranny. After 88 the 700r4 was a lot stronger tranny. If you are towing with a 700r4 tranny it is best not to tow in overdrive.
    As for the 12 bolt issue. Unless you are planning on lifting the K5 and running tires over 33" tall. the 10 bolt should be fine for your needs. I have 10 bolts on my 89 K5 and I tow all the time. I also do a lot of off-roading. So far they are holding up fine. The 3.08 gears are'nt the best for towing. But if you dont go taller than a 31" tire it should be ok. 3.73 or 4.10 would be much better. Just remember if you decide change the gear ratio you have to do it in both axles. If you only change the gear ratio in one axle you can damage the transfer case if you put it in 4 wheel drive.
    Good luck in picking out your new Blazer.

    What's wrong with 3.08 gears? 3.08 gears rule. You don't need those big tires to do off-roading. My truck has plenty of take off power with those 3.08's, hell I beat a honda crx a few weeks ago hehe. And your gas mileage will be so much better plus your engine will not be screaming when you reach 70 on the interstate. 3.08's are the best!

    Another place it could be getting water in, is theres a small round rubber or metal plug in the floorboard, around 1 inch in diameter just above the Catalytic converter, I agree to start run the 10 bolts, till they blow, then upgrade...might take a while however I ran the rear 10 bolt for over 300,000 til I blew the spiders, and the front is still in place. If you decide to run 35's or larger the choice to upgrade will be made for you, because the 10 bolts will go south. I wheel the crap out of the Knight with ten bolts, with 3:08's and 33x12.5...but I do have a very nice 350 bored.030 over..RV Comp Cam..it makes up for the 3:08 ratio, couple with the 208 4hi and the 700r 1st gear it'll damn near lift the front wheels on the ashaplt with the front unlocked. Get the one you like the best and make it do the things you want, upgrade the crap out of it whenever you can, and learn how to improve your off-road driving skills, Those will make up for all kinds of vehicle shortcomings.

    Good Luck
    Happy Trails to you

    Hey Tall Girl - The top may have been not tighten back up right after it was taken off. The best way to insure a good weather-tight seal, is to tighten the bolts on the front edge first, before doing the ones down the sides. Ask if they have removed the top, and see if they used the proper technique to bolt it back in.
    I think tall girls kick ass. My wife of nine years is 6 foot. She hates it, cause she wants to be able to rest her head on my shoulder. Hope you have success in your K5 search. - Gary

    With 2.6:1 low range in the 208 transfer case, 3.08's gears won't be bad off-road and still get decent milage on road. One of my team members lives on your country, so I know what gas cost's there :O. A couple of things to check on that 88, rust under the carpet where it's been leaking, frame cracks around the steering box. The carpet has a padding behind it and if it gets moldy, it will smell forever.

    She's going to be towing a boat and wants to go to 35's. Needs the gears if she can find a clean one with 3.73 that would make it livable.
    Tall go for the cleanest one with the lease body troubles. run 31's for a while till you can locate a 12 bolt or a 14 semi floater with the 6 lug pattern to match your wheels. You can find those on late 80's GM trucks with towing packages.
    I have towed cars 100's of miles with with 3.08's and it's not horrible till you get the big tires. with the smaller tires the 10 bolts will hold up for a while so take your time finding an axle. When yanking the boat out use 4x4 low on the ramp till you get to the top and then put it back into 2 high. That will give you best traction pulling it out of the water and the least stress on the rear axle.
    Now most of us here do hard wheeling and pretty abusive on our trucks. We blow 10 bolts up but the fact of the matter is a lot has to do with the driver.
    While with the 3.08s and the 10 bolt and towing I would stay with the 31's till you can afford a better rear axle and to regear the front. If the truck has been taken care of you may never have a problem with that 10 bolt rear. Pick the truck you like and worry about the gears and axle later. You could probably get away with running the 35's for a while but understand you can't clear them with out a lift so don't waste your energy trying to put them on till you get that. It will probably be a real dog towing but lots of us have done it. Just be easy on it. that big of tire and the 3.08s puts a lot of strain on the tranny.

    I never said there was anything worog with 308s. I'm sure 308s work very well in your 77 with a t400 trans. But Tall Girl is looking at Blazers with a 700r4 transmission. Which has a overdrive. I simply stated that 308s are not the best gears for what she wants to do with her K5.
    Big tall tires, Towing, and 308s will eventually kill a 700r4.
    I like 3.73 Gears with a 700r4 for any tires up to 33" tall .That just seems to be the best all around ratio. A good combination of gas milage and pulling power.
    BTW at 70 on the interstate my 89 blazer with 3.73 gears runs at 2100 RPM in OD .

    Great advice! I use low range for backing my travel trailer up...I just leave the front hubs unlocked. I have a 4 speed so using low range allows me to back up slowly without riding the clutch.

    Ok, I've gone for the 88 with the leak. The others just were too rusty. So now I'm the owner of a 88 K5 with 3.08's TH700R4 and (apparently) a 208.

    It is dark blue, I love it already. Only it has nu hitch. Hope I can get that here. I believe that somebode said that there was a dutch guy on here. What was his name?

    I need to replace the front tires pretty soon, but I already found some 31's. 6 in total in fact so now I can also put the jeep om 31's and keep the 35's for future upgrade.

    I read something about not being able to put 35's under, without lift. Not even on the street. It seems to have enough room under there!

    Anyways. Now that I am an owner too, I guess I'm here to stay. I like to already thank you for all your help so far, but I'm afraid I'm gonna need you guys alot. This is my first chevy.

    Nope the front tires will hit the fender lip in front of the door when you turn with 35's and no lift. My wifes 79 could not fit 33's without hitting.
    Now not all tires that are marked 35 are really 35inches tall. Almost all are shorter. I know that the 35's that BFG sell in the 33 and 35 inch are pretty clos to advertised size. Dunlops run way short. I know a 33 inch dunlop will fit a K5 with no lift where the BFG won't. If you cut the lip off the rear edge of the tire back to the fender liner you might clear them but under compression I can garantee they will hit. With the front sway bar off my 75 and 4 inches of lift I can scrub all 4 tires with 32's. The good news is a 4 inch lift if you leave the front sway bar on and some minor fender trimming will be enough that you will only get minor scrubbing.
    What you need to properly lift these trucks is the following.
    4 inch Lift springs for the front. THe EZ rides are about the least expensive and softest. Here they set us back just over $200 US.
    THe rear has several options. you could go blocks and that would be the cheapest but not great for towing.
    There is the Shackle flip for under $200 in parts. Great for off road but I'm beginning to think it's not the best for towing. I have had some problems with to soft with this sort of lift.
    Really you might want to get new 4 inch springs for the rear. While not the best set up for off road for towing it would be the best and safest.
    you will also need a raised steering arm.
    Plenty of companies sell a kit that will include all of the above With shocks your going to be about $600 US. That's a good price for a vehicle so new. Pretty close to what it costs to lift the typical Jeep. You try to lift something like a Ford Or a Toyota FJ80 of the same vintage you would be over $1500 US just for the front with lift blocks in the rear in the US.
    As for Gears. with 35's the 700R4 and the towing I would say you want to be at 4.56. The OD will take care of the hwy and get you decent fuel economy but be low enough to be good for regular towing. Off road in low with the 2.6 in the transfer case it would be a real stump puller.
