I'm doing a suspension swap on my BH wagon, seems all my notes and preorders missed the fact that the H&R springs I ordered need new spring backs for the top. I can find the actual part numbers, but I am not sure the cross reference. If someone can enlighten me on cross reference, maybe someone has these laying around after a coil over swap. 20325FA000 x 2 (front right/left) 20323FA000 x 2 (front right/left) Thanks !!!
