The 1969 Cragar GT Factory literature (see attached) lists a 14x6 rim for a 69 Camaro with or without disc brakes or 15x6 rim for a 69 Camaro disc brake option. However the 15x6 rim is only listed for a 68 Camaro disc brake application.
The overall dimension of a 68 Camaro 4-piston caliper assembly when installed on the rotor is larger than the 69 Camaro caliper installed therefore requiring the larger 15x6 rim and according to notation 1 requires the corresponding spacer adapter kit 29100 for clearance.
