Check out zcarczar's gallery. He has done a 63" spring swap on a later model blazer.
rdn2blazer, did you trim your spring hanger to clear the support box the 73/75 Blazers have, or did you install a body lift?
Yeah, I installed a small body lift. 1" and 1/8 to be exact. The ord doubler that I first thought about running required a 1 inch minimum to clear the doubler. Even though Im not going to run the ORD Im going to leave the body lift in just incase I need it for the setup I want to run.
