1967 Master Brake Cylinder

[Michael C.]

The question is, What is the correct color for judging ?? The NCRS book says black, but some folks have told me that natural metal color was also factory. Im getting ready for a show, and I do not want to lose points over something as simple as this. Someone of authority please verify the absolute correct 1967 master brake cylinder color. Thank You, Mike Chase

Mike,
My understanding is that master cylinders were painted with a non-permanent black that may or may not have been applied to all units on the assembly line. Those that received paint had varying amounts and some MC had such a thin coat that thew yellow inspection daub showed through the black paint. If your Corvette does not have a black (painted) MC and the judges deduct points, ask them to confer with their team leader. You would probably have a good chance of reversing their deduction.
Good Luck,

Mike - Judges should judge to the TIM&JG. Folks that think otherwise should be working with the Team Leader to revise the TIM&JG and have some good documented evidence basis for the revision. After saying that, MCs I've see on original cars and restored cars have been black as have the NOS GM MCs (not just Corvette MCs) I've found at swap meets. Also, it's been my experience that if you strip a MC and leave it unpainted it will start to corrode, i.e rust. Pete

Keep in mind "unpainted" on a master cylinder would be "as cast", not an easy shade to reproduce (and definately not "cast blast")

Kent - Great information. I trust you have been in contact with Keith Biggers so the '67 TIM&JG can be revised to reflect this information. Pete

The master cylinders were painted at Delco-Moraine, not at St. Louis.
