rear leaf springs

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
