Who has put a B-body 8.75 under their 70 dart?
I put a '70 Challenger 8 3/4" sure grip in a '65 A-Body. Moved the spring perches, adjusted drive shaft length, and just flared the fender wells (could use any wheel/tire combo I wanted after that). I kind of liked the "wide track" look. Of course, it is easier to cut up a four door that a two door, so i am not recommended this for anyone else.
