1973 duster wheel bolt pattern

Shoot, my car is non power manual brakes, manual non power steering with front 10" disc brakes. My last 73 duster (exact same color, just coincidence) was also non power brakes, manual steering and still had 10" front disc brakes drum big bolt rear. The only difference being this one now is mixed bolt patterns. So from my experience they did build manual non power front disc brakes in bbp. As for the b-body rearend, I did consider it initially. In doing research and talking with a few guys who have used them they all said they wished they would have gone with the correct A-body rearend as ever time they put a full tank of gas in there the car would rub tires on the fender lips, especially with any passengers in the back seat. I do agree the tires look too small on A-bodies with a stock rearend.
