'73 C-body disks; what master cylinder? - 08/02/13 03:05 PM
I've got all the stuff for the '73 swap, but I'm not sure which MC to get. I'm wanting to run manual, but I don't see any options in terms of '73 manual MCs. Is my only option to use a power MC with a manual pushrod?

Master cylinders aren't body specific. They all fit. Just find whatever application has manual discs and go from there. Look for one with a 15/16" bore if you can.
Also if you are going with manual brakes make sure you have a manual brake pedal set up. The pedal ratio is different power to manual.

Cool, thank you. I had a hunch they were all about the same, but I wasn't sure if the mounting differed from body to body. As for the pedal setup, part of the allure of a manual setup is that my car has manual drums already. Well, that and I don't want to have to worry about pulling enough vacuum.

I have read a lot of guys like to go with a later 2 bolt aluminum master for a light 80's truck. There is an adapter plate for this swap.

Get a 69 or 70 C body master for disc drum.I run them on all my conversions.I assume you are installing the discs on a C body.My 65 B has one on now been on at least 12 years and my kids 62 300 has the same with power drum drum.Mine are manual disc.Rocky

Yep, I just used a 73 C body Manual Master when I converted the 65 Newport
