Looked through the tech archives but couldn't find the answer, so I'll ask it here.

Have a friend doing a disc brake swap on a 66 Belvedere that is a drum brake, single line master cylinder. He has all the disc parts off of a 1974 Dart, including the proportioning valve.

Trying to find out what master cylinder I need to order that will work. His car does not have power brakes. Will he need to find a different brake rod, or will his work if we get the right master cylinder?

Thanks
Dan
