Is the width of a 68 b-body rear the same as a truck rear??? if not whats the difference???? will the leaf springs line up w/the plates and pins I took rear to local shop and I'm wandering if they could have switched it out on me. put on new super stock leaf springs w/275-60-15 tires on 10" wheels and tires rub pretty bad..
