    I've studied this a little for my crew cab. The easiest way to do it is with a GM nv4500 bolted to a 85+ (round pattern) 205. If you use the OE long t-case input there is a spacer ring from AA you'll need, if you swap in a 84- short input the combo will bolt together as is. The t-case shifter will have to be a custom set up as there will be no threaded boss for the 205 stick (like with an OE adapter).

    I'm not sure what to do about floor board or tranny mount issues (or if there are any). The MOO Suburban has a nv4500 so they could answer fitment questions but theirs is bolted to a Doubler so they may/may not be able to answer other questions (since they didn't have to deal with the mount, shifter,etc).

    Be sure to post up anything else you find out or do. :thumb:

    I have the round pattern 205 in my truck .i just lost the clutch disc and have everything out right now. it sure would be nice to slip in an overdrive right now. the checking i have done i dont think i would have to change drive lines.the nv 4500 set up would be only .125" longer than the present setup.my 465 leaks pretty good . so i am trying to decide to over haul it or pony up for a new tranny.anybody know of a killer deal on a nv right now? thanks
