Which leaf springs to use?

I bought mine from Summit at the end of last year. Mopar part numbers and Made In Mexico stamped on them. Luckily I like Mexicans so it doesn’t bother me.

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 ....
