ID help with a master cylinder - please

[Roger O.]

I have a master cylinder that I would like to ID if possible.
The # as I read it is 5460346. The last number is partially rubbed off . One or both of the 6s could be 8s . I have the complete master and booster and have a suspicion they are from a 73. Thanks for any help.

It's a 1-1/8" bore master cylinder used for 1967 with J-56 as well as most, if not all, 1968-82 with J-50 power brakes.

The 1967-about 1972 versions have bleeder valves. The about 1973+ versions have no bleeder valves.

"PG" is the most common stamped code, but a few other codes were also used, especially for later C3's.

Joe,

Thank you very much. It does not have bleeders so my suspicion of a 73 is probably close.
