Did you ever find what you need?
I have 2 sets new.
1 set of Comp. springs that are brand new, w/2 sets of retainers w/ superlocks.
One set of springs came new on the assembled Brodix heads I bought new, the other set came in a Comp kit for a .575 lift solid. I am not at home so can't give the Comp numbers off hand.
I'll never use them, so they will be CHEAP!!
