Master cylinder code
 

working on a sept of 68 1969 z car and the master cylinder looks like its never been off the car but the stamped code is PG & not US can this be correct

PG is the code for a Power Brake Corvette. 67-72E

Should be US for sure.

What is the code on a JL8?

The PG has a 1-1/16" bore if memory serves... I put a kit in the one on my Corvette this summer.

master cylinder
 

The pilot 69 Z28 that Larry Christensen had at MCACN had a different master cylinder that was not a "US", as I recall. I only bring this up as question as to what may have been on very early 69 cars. I have owned a 10B of 68 Norwood and LA 69 Z28's and both had US master cylinders.

Some very early 69's had the 68 coded Master.

That would be "WT"....Joe

Looking for a thread that has application codes for "409" Master Cylinder

EB = 70 Camaro
BB = 70 Chevelle

CF = ????????

CS = 1973 Camaro
