what ive heard that the AW4 transmission wont fit into wrangler without movin the engine more forward in the engineroom, and lowerin the transmission and puttin some 2degree shift on the rearaxle towards the transfergear...and at that point rear driveshaft(cvjoint) with sye-kit might turn without "grinding".
thats what i saw on one such project.
ie, the aw4 is much longer gearbox than the tf909 that is originally in wrangler yj

Its only about an inch longer than the ax-15 so your info isn't quite right.

I did this swap, most tedious part is wiring. The rest is basic mechanic and fab work.

You wiring will be different than what I did due to yours being an OBDI era AW4 and mine was a RENIX (pre 91).

I'll see if I can't find some info on OBDI wiring, but I know there are a couple guys who have done that swap specifically that I'm sure will chime in.

EDIT:
Here is some generic wiring stuff I have, don't assume my hand drawn connector list will work with your transmission's control module because I used a RENIX era one.

Also, "meangreeny" helped me out tremendously and IIRC he did an OBDI swap.

Also, more info here. You'll have to sort through what you want to use since this was an OBDII swap:

And a RENIX version swap:

These will give you an idea, but like I said, a couple of the pins for the wiring will be different.

ok, thats only what i saw and heard about the project they did here, the rear driveshafts angle went so steep that it started...damn dunno all the tech words in english, well started grinding against the joints specially when flexin the suspension, ie the driveshaft didnt rotate freely...
and that was with 3inch lift, So it may not prove difficulties in stock suspension...

I'm in the middle of this swap on my 94 right now. Plenty of people have done this. Looks like my rear shaft will fit just fine, but my front driveshaft is going to be too short.
