Non A-body mopar question

Well I wouldn't want one. I've had f bodies (Aspen/volare) with that rear and my first Dakota with a non magnum 3.9 had one and I blew it to smithereens not even being hard on it.
I replaced it with an 8-1/4.
If the car is otherwise nice, and the price isn't crazy id buy it even if it had a 7-1/4 but would looking for a better rear end constantly until I found one, whether I blew the 7-1/4 or not.
