    The 75 has a 12 bolt, everything was rebuilt. The 86 has a 10 bolt and no TBI, do you know what kind of condition the engine/tranny etc. is in? Also doen't the 75 have a full removable hard top if you want to have the top off a lot you may like that more.

    Definitely go for the 75. Depending on where you live inspection, emmisions and modification laws will be your downfall with anything too new. You can pretty much do any mods you want with something 27 years old and the state cant say anything about it. I'll bet it never had a catalytic converter or an air pump or any other smog BS. That means that if you want headers and dual exhaust you can and a big open air cleaner too.
    Remember the old days when a state inspection consisted of checking your lights, wipers and your horn? Those days can be yours again. Get the 75.

    yeah go with the 75, i just bought a 73 and though it's a rust bucket i wouldn't trade it for anything. If you or anyone else needs the side glasses for your hard top I have two I will sell for cheap. I made a half top and am rigging my own tonneau cover to cover the back end....peace.

    Just so ya know the 74 and up did have cats and the a.i.r.pumps. If your smog check is like CA then you need to keep that crap....BUT my vote is still for the 75.

    I say 86, but I am partial. I would definatly say the 86 if it has power windows, door locks, cruise control, you know the creature comforts.

    I have an 86' and I need a new carb. As much as I'd like to beef up the carb and put headers on, I can't because of smog crap. Get the 75!

    Go with 75 I have a 73 and they rock, only problem is the emissions right here in california they still ask for the smog check on a 75 but if you have everything you should be fine.

    According to my paperwork, the GMC Jimmy was not equipped with the cat or air pump. It was equipped with "heavy duty emissions" just like the 3/4 ton pickup. The 1/2 ton pickup had all the emissions stuff but the Jimmy did not. I dont know what the reason is but my stuff says that it is so. I am sure that California is different.

    I have a california 75 that came with the Heavy duty 350 (Family 113, i think) it came with a pump but no cat, and no egr,, and i've never gotten grief over my dual exhaust, altough i do still have the stock manifolds. But in answer to the original question, 75 definitely, on a 75 you can acctually see teh engine, on an 86 you have to find it under all the hoses and wires and crap, and you might get lost along the way, and pulled into that jungle of tubes and never seen again/forums/images/icons/smile.gif so for style and safty sake/forums/images/icons/wink.gif get the 75.

    Hey Leland. Really? A pump and no cat? I don't have either on mine (federal version), and I'm sure it came that way from the factory. What's the GVWR on your 75? And did I read it right, it's a California truck, ie CA emissions?

    in a few years, the 75 will hit 30 and you wont have to worry about emissions unless they change the laws again. plus on the 75, you can bolt up a 91 font clip with a little mod if you wife likes. it will look newer then the 86 and have power windows, mirrors and tail gate if you want.

    Ya, California emissions, but it rolled off the line in late 74 so......they probably got away with it, plus it was the heavy duty engine, with heavy duty emmisions at least thats what the sticker on the aircleaner says, i think the GVWR is around 6300 lbs but thats just from memory.
