the pin spacing on the 4 piston early Bird calipers is the same for the 4 piston '67-68 A body caliper, but there is something different aboutthe original Firebird piece. It may be the angle of the casting where the boss is for the hose to attach, that's how it was for the '69 single piston calipers. Interestingly, the original Bird 4 piston calipers have larger diam caliper bores than ones used on Novas and early Camaro's. Desiring to have the original calipers rebuilt/resleeved, check with White Post in Virginia.
