To give you a little more education on disc brake kits for your car. Any kit that uses a 1 piece rotor (69-72 Chevelle rotor)that bolts to the stock spindle moves out 3/4", OK as long as you don't go wider then a 7" wheel with 4" to 4.5" back space. Drop spindles don't move out as much, about 5/16". The zero offset kits keep drum brake location, not that big of a deal on 59-64 but some people prefer that. The zero offset plus fits original 14" steel wheels is my exclusive. All other disc brake kits, including 2" drop kits will not fit 14" original steel wheels. Just in case you wanted to go back to original.
