While it does have a true "AMC bolt pattern" (no adapters needed at the block), I believe the rear of the case is such that it's very hard & expensive to convert. FWIW, lot's of folks swear by the QT... the bad word comes from them
never changing the "special fluid" & chain, then wondering why it laid down on them!
(parts are available).
If you need to search for a "Jeep" (
Buick-
Olds-
Pontiac) TH-400, they came in jeepsters, Commandos, Waggy's & J-trucks. He'd need the cast iron ring that mates the block, the spacer for the crank flange, & possibly a different offset flexplate. If your looking for a Jeep TH-400 setup for a D20, LMK... I have some connections
While this will probably bring out the flames
, it won't hurt a thing to run the QT with a centered diff... in reality, the driveshaft sees only one angle.... whether it's centered & down to diff or offset to one side (my 304/TH-400/D20 sits 3" to starboard & the pinion is centered... from the factory)
