Hi everyone, I'm looking at buying some used Hotchkis leaf springs. #2407C (24910014) is the 1.5" drop; #2413C(24910015) is the 3" drop. I'm looking at buying the 3" drop ones but the seller doesn't have any markings left on the springs and he didn't buy them new. Does anyone know visually the difference between the two? Does one have 3 leafs and the other have 4!
