A 67-8 master for manual brakes will fit either the stock 64-66 booster or straight to the firewall IIRC. If you decide to go disc a 71-2 manual master fits the stock 64-66 booster. There is a TEE in the brake line under the engine, replace this with a coupler to couple the front lnes back together, then add the second line down to the rear line that was previously attached to the TEE.
