manual front drum to KH disc swap

This is a quote from 340sFastback in my build thread, and is what I did. Mine are manual brakes. They work great.

"I recommend a 15/16" master cylinder for reduced leg effort. Order one for a '73 340 Duster with power disc brakes. It will bolt right in to a manual brake car. 7/8" rear wheel cylinders help to balance the brake system too along with a proportioning valve."
