Which tranny would mount upto the D300 the best?

I have a 73 CJ-5 with a 4.2 (might go with a 4.5 stroker, since I have a complete 4.0 laying around (no wiring)) that has a 3 speed manual. I am thinking about swapping out the trans/t-case for one of the auto's below and a D300 that I have laying around. The main goal is to use a many stock parts as possible without any adapters. Here are the trannies:

TF 727: I have read that these will bolt to the D300 fairly easily, but requires a lift (considering the suspension is SHOT, that isn't a concern). The hard part is the kickdown linkage and their availability.

TF 904/909: I can get the 904's and perhaps a 909 fairly easily. However, I have NO idea if any of them will bolt upto the D300 without an adapter. Plus, the 904/909 will require some minor fab work to get the kickdown linkage to work properly. The concern I have with the 904/909 is the weaker case issues.

TF 999: I think this tranny might be easier to find and require the least amount of fabrication to make the kickdown linkage to work. However, much like the 904/909, I do not know if it will mate upto the D300 easily or not. Though not as strong as the TF 727, it has a stronger case design than the 904/909. BUT, it might be too long for the CJ-5.

Let me know which combo would require no adapters and fit the CJ-5 the best. Thanks!!

The TF999, if removed from a Dana300, will be a bolt on.

The TF727 would require a 4" lift, or modification of the ATF pan.
