My bro in law is in the process of playing with one of his many dana 20's.He was wondering if it is possible for front drive only?I belive it requires some detent balls removed but don't know about anything else.Does anybody have the low down on this and is it possible?Thanks in advance. <IMG SRC="smilies/confused.gif" border="0">

I know that you can twin stick the dana 20 in the Scout II's. That set up uses the sticks from a dana 18, I've also heard that you can use the Currie twin stick set up with some light mods. Try doing a search. <IMG SRC="smilies/smile.gif" border="0">

You can do any of them, but what you end up with depends on which dana 20 you have, because they shift differently.

My early bronco 20, one stick controls rear axle, one front, so now that I removed the lockout pins I can get rwd, fwd, or 4wd in high or low range. However, without the lockout pins it IS possible to put one in high and one in low.

If I am not mistaken, the jeep 20 one stick controls 2wd/4wd, the other hi or low range, so I'm not sure that twin sticking would get the results you want.

On mine, in order to get fwd you have to remove the lockout pins. They are located BETWEEN the shift rails. This means that you have to get the shift rails out in order to remove the pins, which means basically disassembling the entire transfer case to get the shift rails out.

Hope this helps.

There is a guy on this BB that lives in
Hawaii that twin-sticked his CJ D20. I can't
remember his name. He even has a how to with
drawings on his website.

I just did it to my Scout II D20, which should be the same for Jeep D20. D18, and early D20's had twin sticks. In order to use front wheel drive you have to remove the interlock pills, not the detent balls (won't stay in gear if you do that). If you use an early D20 TS, disassemble the case and pull the shift rods. Disassemble your case and swap the rods, and sticks minus the interlock pills. If you do not use the shift rods from the early D20 then you have to modify the stock rods, (Jim Weed Twin Stick) The currie kit is nice if you do not have the early D20 shift rods.

It is possible to only convert to TS and not remove the interlock pills, you will be able to get into rear 2wd low but not front only. It was nice to have the rear 2wd low when running around on the slabs.

Thanks for the help.We were playing around with it last night a bit and kinda figured it would be balls with a tough spring in between the rails but a solid piece makes sense.I assume that it is an early case.What were the year breaks if anyone has that info.It looks like the shift pattern allows the front to be engaged but we weren't sure.Each rod has three settings and one seems to only control the front for high and low with a neutral in between.I guess we'll have to rip it apart and find out.Trouble is which case to use and if they are right or not.

You have to pull the shift rails all the way out and remove the interlock pills. Then you can shift each rail independantly.

here's a pic of a Dana18 (for what i know, the d20 is very similar)

one shift rail controls (2wd-4wd), the other (hi-n-low)... if you take out the 2 detendent balls (yeah...) ... you get 2wd-low, as both rails can now work independently

My dana 20 is an Early Bronco J-shift. No modifications are required to get front wheel drive. Just twin stick it and it's done.

The later T-shift case I was able to get two low front and did not need to pull the case apart or remove anything. The J-shift case I did later for the lower gears I did have to pull apart to get the shift pills if that is what they are called. But don't remove the detents or you will end up with a case that shifts it self form my experance!
Good Luck. <IMG SRC="smilies/usa.gif" border="0"> <IMG SRC="smilies/beer.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0">

I guess I am a little late in my reply, oh well. Yea, I messed with it. Haven't finished yet though. Looks fairly easy. Hardest part is removing the interlock pin. After that you just have to fab up some linkage and arms. Don't quite know what to do for a boot yet. I am only doing mine to be cool <IMG SRC="smilies/rolleyes.gif" border="0"> , and to eliminate some of the linkage from the single stick.
