    I think there are a couple floating around. Someone was going to try and produce (reproduce) some recently and a while back it was the same story. I've tried to get some solid information both times in order to make my own or even buy one. Something has happened both times and I still don't know. One of the 4x4 shops used to make them but they were toooo much money. This is just what I can remember from my time here. I'm still interested as it would seem are others. We'll see, I'm sure they will pop back up sooner or later.

    This is what I (think I) understand but I have never done it. It is on the "to do" list for my new project (which is not even running yet).

    It is fairly easy to twin-stick a 205, the hard part is rigging up the twin stick. There are 2 shift rods, one controls the link to the front shaft and one controls the back. The only thing preventing the separate operation is a interlock detent ball which can be removed from the outside of the case. The detent is under the (5/8” ??) plug just over the outboard shift rod and can be removed with a small magnet. The only hard part is finding a twin stick to work the rods separately, this is where you will need fab skills.

    However, there is one problem with doing it like this. There is nothing to stop you from putting the front and back into different ranges (low front/high rear) which will be likely to break something. Not good! In the August 2000 Peterson's there is an article on modifying the 205 for twin-stick safely by doing a little grinding on the shift rods and retaining the detent balls. They also show a twin stick for a Dana 300 that they modified for a 205 but they never show it after modification. This is what I plan to use when I get to that stage...

    There's a place down the road from my parents' house that makes one. They are called Down East Off-road. I've been trying to find info on it, but can't seem to find any. They used to have it on their website, but not anymore. I know they still make it, though. If you want me to, I'll get in touch with them and see what I can come up with.

    I did mine by doing the grinding on the front wheel shift rail. I have not used it yet, still putting the truck back together. It was simple, but I did not grind enough and I only have front wheel low, but dont need hi anyway. The advantage is having rear low 2wd and front low to make really sharp turns with. From the preliminary looks I can operate it with the single stick shifter still. My 205 has the offset linkage though if you have the straight linkage I dont think it will work with the single lever.

    I thought I was wrong once,
    but I was mistaken

    Hey Butch
    I'm still not gittin' it.
    Wouldn't that have the same effect as 4lo and the gearbox in low(sm465). That's what is in my rig.
    Don't think I'm being a smart a$$, but the front wheels are are only going to turn so far untill they contact the stops.
    I have seen rigs in Petersons with a twin stick 205.
    And have always wondered why.
    I know that the axles being in 2 different ranges is bad news(one high one lo)
    BTW I am kinda new to the 4x4 scene.
    See ya

    There's a lot of times out in the boonies when it would be nice to be able to stay in low range, but not in 4WD. Moab is a great example. The rocks there have a surface like sandpaper so staying in 4WD in some spots tends to bind up your drivetrain. And if you have lockers front and back then steering becomes a major PITA. Shifting to 2 Low makes it way easier to get around in places like that.

    Thanx Harry
    That clears it up.
    So let me see if I have this down.
    You would want the rear axle in 2 low and low and the front axle would be in the neutral position?
    Like so

    The other range it can be in is Front wheel low range/ Rear wheel nuetral. This is (apparently) useful if you engage the parking brake you can pivot the truck around an obstacle easier...

    I too wondered about this..............I know this sounds silly, but is this advantage not the same as getting out of the truck and unlocking your hubs?

    Hey Frank, I think the advantage (to some) is having front wheel low range/rear wheels nuetral. I believe the only other T-case capable of that is the Atlas II...
    For 2 wheel low (rear wheels) I just don't lock my hubs. I use this for backing up my trailer. With a standard it beats riding the clutch.

    At one time, I was able to swing the front end around on a nerrow trail and go back the way I came. (backed the rear bumper into the mountain, cranked the wheel and gave it some go). I did not have a dual shifter on the t-case and it was a muddy trail, but after doing that I could see how usefull a dual pattern T-case could be. If I could have unlocked the rear and just used the front, would have worked even better!

    Yep, same concept. But after you've held up your entire trail party 50 times to lock and another 50 times to unlock your hubs and it ain't even lunch time yet, you get an appreciation for just being able to yank one of the levers on the floor. [​IMG] Not nearly as useful for playing in the mud. You'd have to drive around on the rocks at Moab to get a full appreciation of how useful such gadgetry can be. [​IMG]
