8 1/4 rear question

perches are a little wider on the b-body. some weld new perches, some just spread the springs, some oval the spring perch holes on the b-body rear end and spread the springs just a tad. This last is my preferred way
Yup this is what I will do since I have a 8 3/4 out of a 70 charger........that made me cry she was too far gone! She only cost $100 tho.
