ORD does not include new brake rotors or calipers with their kit because these items are readily available at just about any local auto parts store or wrecking yard. Due to the high weight of these items, it simply does not make sense to ship them by mail. This helps keep the cost of the conversion down. To complete the conversion, the customer must source a pair of brake rotors from a '73-'87 GM 3/4-ton front axle and calipers from a '73-'87 1/2- or 3/4-ton front axle. We purchased this set recently from Boyce Equipment in Ogden, Utah.
