Title: '69 Z/28 master cylinder
Post by: GaryL on June 21, 2009, 07:52:53 PM
I saw a well documented Z/28 yesterday. The master cylinder was stamped "PG" where the "US" would normally be. Could this be a factory replacement? If not what was a "PG" master used on?

It was used on '67 Corvettes with J56 Heavy-Duty brakes (with an adjustable rear proportioning valve), and on many '68-up Corvettes.
