I totally agree with Rod on the budget friendly 4 link. I had bad luck with leaf springs on my 68 Firebird in the past. I had a set of Hotchkis leafs snap completely in half on a non track car going 35mph up hill. And yet another set of Hotchkis leafs with a faulty locator pin which caused my wheel bend my sheet metal. In my opinion they aren't too bad when used with a quality shock but once I installed the 4 link it was night and day. The set up Robs brought up is an amazing value.
