Which master cylinder for my app?

I'm ready to plumb the brakes on my roadster and I'm not sure which master cylinder would be best to use. The front has '55 f100 drum brakes and the rear has an early bronco 9" with 11" drums. I am using the pete and jakes floor mount pedal assembly. Do I want the early corvette style, '68 mustang style, or ? Please let me know what you think!! Thanks in advance.

 

Since you have a "drum and drum" setup, whatever is a clean fit and you have available should work fine. I just put the Corvette style on my '41. I would suggest going a 1" bore, that way if you decide to go disc/drum, or even power disc/drum, you can use the same M/C. My coupe has a Ford style under floor set-up that works fine. Just remember to put residual pressure valves in your system, in your case with drum/drum, go 10lb front and rear. I put mine in where I was going to need a union anyway, so they served a double purpose.

 

Thank you for the awesome input. What year 'vette should I ask for?

 

Seems to me any of the mid-size GM cars used that same M/C. Ask for something late '60s to mid 70s. I think mine cost less than $30 bucks new. Clamp it in a vise and "bench bleed" it first. That will save much "swearing and knashing of teeth" later.
