Going to be cleaning up this mess on this too long forgotten car and replacing the MC on my 69' Cuda and hoping that somebody can help me ID this one, possibly from the markings. The car had this raised one on an aluminum plate when I bought it many moons ago and I alway's thought it kinda odd and hardly factory but it did work, i' m not sure that it's a Std 69' Cuda MC and since i'ma have to surely order one I just wanted to hopefully order the correct one.....has a 1" piston.
