Would like to install a dual master cylinder on my 40 ford. Right now I have a full stock system. Is there a kit available to make this easy?

If you get a 3 bolt to 2 bolt adapter like in the following link; you can use a regular '67 Mustang drum/drum master which has built in residual valves. The 3 bolt aftermarket master will require the addition of external residual valves.

Carrillo Customs sells a dual reservoir master cylinder cast with the 3 bolt mount. Josh is great to deal with and very knowledgeable. Here's a website link to it:
