I have a 95 C1500 stepside lowered 4 in front and 4 in back (I didn't do it I just bought it and they cut 2 twists off the front springs and took a leaf out of the back and used a dropped spring hangar) My question is this; I just bought some used 18" wheels with 6 inch backspacing and I'm wondering if they will work? Thanks ahead of time for any help guys.
