Power DISC brakes? Never came on these cars. Could have been added with parts from a later model, but I'd double-check on that point.
It is a good looking car, the A/C and the Master Cylinder are not original. I bet the brakes came from the same car the engine and trans did. Looks like a nice conversion using mostly Olds Parts (exept for the A/C) But priced to high for me wallet. I would probably like it better if it still had the 394 Olds V-8, with an OD Automatic and with the Disc Brake and A/C Conversion.
If I ever buy a 1963 car, I want a 1963 car. Okay if somebody wants a mixture of years, but I want the real deal. Pretty car though, I've always loved the '61-'64 Oldsmobiles.
