Car originally had 4 wheel drum manual brakes. I pulled off the manual master cylinder and used it to replace a worn out unit on my '65 4 door. Now, I recently acquired a power master cylinder off a '66 that had the same 4 wheel manual brakes. From everything I read, this should be a bolt in set up that will work just fine. I have two questions though.. is it truly a bolt on set up, and there is nothing else that needs changed? Secondly, Where do the vacuum lines run to and is there a place to order these? OR is it just a standard size rubber line that I can get at the hardware store. Motor is non stock, '77 403.
