I am converting my 67 stang to disc front brakes. I am using 72 mustang parts. I have one final part to buy, the master cylinder. Does anybody know what master cylinder will bolt up to my 67 and work with this application. Also, the car is manual brake not power. Okay while I'm at it one more question, can I use the stock proportioning valve from the drum brake application? I wasn't sure, so I took the proportioning valve off a 70 Mustang that had manual disc brakes but it looks identical to the proportioning valve that is being used for my drum brakes. Thanks, I hope somebody can help me solve this riddle.
