Linkage is likely to be different, possibly a different converter and maybe a different drive shaft length. Can’t remember if the 2wd truck trans were the same length as cars or not.
If I recall right, the 727 we procured from a van and transplanted into the Challenger TA was about 4" shorter than the 833 we shoved over in the corner. A used Mustang shifter, some creative torch work on the linkage and off we went.
