Delayed response. I bought a conversion for my 57 300 and 57 Imperial. Roger w/ AAJ brakes said to use a 69-70 disc/drum MC. This does does not need and modifications. Napa quoted me on a 3901B at $43.41. I get a commercial discount so not all may get that price. This # is for my Imperial I assume the 300C would be same. Second choice is a 76 Dart. The wire clip that holds cap on requires modification the clear brake booster.

Happy Weekend to Everyone out there in 300 Land! Planning on doing a disc brake conversion on Big Red (59 300E). It has been recommended that I replace my existing master cylinder. Does anyone out there know where can I acquire the right master cylinder? Thanks!
