Again I can't find the post that I am looking for. I am swapping out the front 4" Rancho springs next week for 6" TC's. I am also doing a 5.5" Echobit shackle flip in the rear with a 1" e-zero rate. I remember (I think it was Greg) talking about swapping later model rear springs in for ours because they are softer than ours. Can't remember if they were early 80's springs that he was talking about or what. /forums/images/graemlins/dunno.gif I don't want to have to make any modifications to use them. If someone knows the years that I am talking about with the softer rear springs that will (hopefully) bolt right in let me know. Thanks!
