Could someone tell me if all 68 Camaros had bleeders on the master cylinders and were the 11" delco morraine boosters only for certain models or brake setups.
My manual drum brake car has no bleed screws on the MC and (obviously) no booster.
So, I guess the answers to your questions are No and Yes, respectively.
