I have used M35 masters in 2 CCKWs now. Yes, the brake light SW
may be an issue. I retrofit all of mine with a mechanical lever type switch
so that the minute I touch the brake pedal, the brake lights come on just
like a modern vehicle. I do this for safety. It is a brake light switch from
a 1957 Chevy PU truck.

The last master I got seemed to be a bit narrowrer then the original. When
tightened in the mounting "box", it caused the arm to bind. I inserted a
couple
flat washers on one side and that did the trick. I got both of my M35
masters from VT Commercial Salvage and they had all the holes I needed
drilled and tapped.

If you want the original, I second White Post. I have had a number of wheel
cylinders sleeved by them w/o problem.
