New to the forum and new owner of a 55 T Bird. Anyone seen a 55 master cylinder that is rectangular in shape with two brake lines coming out of the master cylinder? Looks like it has two pistons or ports in the master cylinder. I can't find anything that looks like it on the T Bird sites. The car has been in dry covered storage for over 30 years and of course the master cylinder was dry as a bone. It has a rectangular lid that has a long bolt that holds the cap on. I had to remove the drivers side hood latch to get the cap off. It also has 56 side wings and what I believe to be a 312 with a big Holley carb on it. It clearly has a 312 intake and exhaust manifolds but I will have to see the crank to find out if it has a notch in it to determine if it is really a 312 or not. I must admit the master cylinder has me stumped. Might just put a 67 Mustang dual bowl on it like I did my Comets and Ranchero's. Any help would be appreciated.
