Which leaf springs to use?

liking mexicans has nothing to do with it , I have set that was on an A body race car , and the 002 is bent just in front of the rear spring hangar . I swithched some leafs out and supported the bent one more , but havent tried them ....
Are you talking about new or used springs? If you bought a set of used springs from a race car and they are bent you can hardly blame the springs. If you bought new springs that were bent you should have exchanged them.
