According to my information, all AOD's are the same, externally, with the exception of the length difference on the Lincoln/Truck units. Internally, V6 AOD's had less clutches than the 5.0 units.
This tells us, that the bellhousing is the same on the 3.8 and the 5.0. So my answer to your question is: your typical T5 should be fine. You'll have to find the right flywheel, and pinion bearing, yourself. I would think that the 5.0 or the 4 cyl pinion would be fine.
If you want to do this swap inexpensively, I would say to use the stuff from a 4 cyl Mustang T5 or a 5 spd Turbocoupe. That will get you started more quickly, and get you the steeper gearing in the 4 cyl transmission. Again, before you make your decision, you need to find out what size the pinion bearing would be on a 3.8.
Many 5.0 Mustang guys run the 4 cyl T5's, and indicate that they're almost as durable as the V8 T5, if that makes you feel any better. :)
I'm interested in a set with adjustment, as well. It would be awesome if you could make them in stock, up to about 1-1/2" - 2" lift. That would be perfect!
At the very least, I need to have 3/4" spring spacers added, I see Global West sells those, albeit not cheap (at almost $60 a pair!).
I am sure the adjustability would benefit your Mustang arms as well.
Keep us up-to-date on the changes being offered. We appreciate your attention!
