Doing the best that I can
Can anyone tell me if Super Stock rear leaf springs, will work on a street car. Will they bolt right in or do the perches need to be moved ?
Sure, they'll bolt right in and work on the street. The ride will be stiffer and they'll raise the back of your car - and the back bumper won't be level.
What is your car's purpose? Strictly street or street/strip?
If strictly street, you may be better off using a matched pair of HD leaf springs from ESPO

IIRC, I think the front bolt is larger on the SS spring,, so you may have to drill out the front spring perch hole...
hope it helps
