Homebuilt D18 Twin Stick?

With the LR in the font of the CJ now, it seems really helpful if I could figure out a twin stick conversion for the D18 so I can run in 2lo (especially with manual steering). I did post a WTB in the classifieds, but it also seems from a recent thread, that many think it would be a pretty easy homefab to convert my single stick to a twin stick? I don't really have a good idea of how to start thinking about that....anyone got suggestions or pics?

thanks

 

if I can get one for reasonable price....also, twin sticks and 4speeds can be a PITA, so maybe starting with the single stick cap might provide more manipulation to fit everything together (including the OD)? worst case, i could steal the one off the 58 and swap it with the cj. Heck, I keep thinking of just swapping the entire 465/D18 into the cj and using the T18 and TL D18 in the 58.

 

I had to grind a lot more than that to fit the twin stick with the sm465

 

The D18 shift rails for the single stick and twin stick are the same? Basically, if I found a front twin stick cap, I can use that cap with my existing shift rails (which one has been cut down a bit to fit the TL gears)?

 

Guess what I am asking is if the total length and diameter of the rails is the same....such that I could grind out shift lever notches if needed - or whatever I can come up with for the levers, as I don't have a set of those anyway.....
