Default Master Cylinder

I'm going to switch my front brakes over to disc's using scarebirds adapters and need to know what master cylinder works best with original booster. This is for a 63 Catalina.

When I did the conversion on my 63 Grand Prix I ordered this master cylinder:

http://www.mpbrakes.com/products/pro...product_id=534 It has the deep hole that mated with my stock booster and the ports are on the right side which made the plumbing a little easier. I also ordered the proportioning valve from them.

I dimpled my inner fender to get the lines in, like Mike said its a tight fit.

The correct master will depend on what power booster you have. Deep hole or shallow hole.

I used the Raybestos MC36361 master cyl from NAPA and the Summit adjustable proportion valve (SUM-G3905) with the Master Power (VL3526) Metering Valve.

That looks like a pretty tight fit. I have the Delco-Moraine master cylinder and booster. The 67 GP master with lines on the engine side looks like it might be a better fit.
