    Good morning to all! Before going out to move some snow this morning:BangHead: I am doing some brake research. I am working on obtaining all the parts to convert my '68 to the '73 front disc setup....fingers crossed! There is plenty of info on the power to manual swap for A&B bodies, so I know it is very common. I am leaning toward a 15/16" bore master cylinder. I have searched here and can't find much. Has anyone done this to a C-body? Need to find out if I need a plate on the firewall, what rod to use, how brake proportioning should be accommodated, if the pedal assembly will need to be modified, ect.? I feel that this is a worthy modification....better feel and control of the brakes...if done properly. Your thoughts and comments are very much appreciated!:sSig_thanks:

    Since your car is already power I'd go with the dual diaphragm disc brake booster, and the disc brake master cylinder and call it good. If you want to go manual you need the manual specific pedal and arm, the manual specific rod you can reuse your plate just drill 2 holes you'll also need 4 studs that retain the master to the plate. 66-68 manual pedal assembly.

    I converted my 65 Fury to manual disk brakes (from manual drum) way back in the 80's. One of the best things I ever did to the car. I had a 73 Monaco I was stripping and noticed the similarities. Everything just bolted in place, it was incredible. I used a manual master cylinder for a 76 Volare and the proportioning valve from the 73 Monaco. Only regret at the time was I had to go up to 15 inch rims (unless I went with smaller rotors). It was a small price to pay for awesome stopping power. I drag race the car and it would easily take me the entire shutdown area to slow the car down (on all drums). Afterwards, I could stop in less than half the distance and make the first turn off. On a side note, my car was originally equipped with front 3 inch drum brakes and 2 1/2 rear brakes. The difference in stopping power with the disc conversion defies description and is a simple bolt on deal with factory parts. Also, I prefer manual brakes but to each his own. If you convert from power to manual, you just need to do more research as the pedal ratio is different between the two.

    Thanks guys. I guess I am looking for a manual brake pedal assembly from a '66 to '68.It appears that the MC from a 1988 manual brake Dakota is what I am looking for also.

    I went with the Volare Master cylinder because it looked more correct in a 1965 car.

    Problem is you'll need the 4 bolt to 2 bolt adapter to mount the 88 master cylinder.
