Is a CS master cyl correct for a 74 T/A with PDB? If so I`m looking for one.

Thanks KC

Where are they stamped?" I have mine soaking for a rebuild and can check in the morning.

Yes, they are. Here is one on a 12K original, read CS (application) 4 (year) and 198 (July 17th, Julian date)

Same on mine except one day newer. Also the casting numbers if that helps.

Thanks, HFR is that master stamped on the front pad also? And does it have bleeders?

It is, more or less, the front pad. They had the pad for bleeders, just no bleeder. This one is June 27th, 1974.

This one is stamped a little different with the cs last so it`s either 319 day of 70 or 190 day of 73 and it has bleeders. Thanks for your help.

Yup, July 9th, 1973.
This one is June 14th, 1973. 3165CS. Bleeders.

Here is the one from my Oct. '73 built '74.
Sept. 10th, 1973. CS3253.

So, when did they start with the small stamping with the Julian date by the bleeders instead of the larger 2 letter code stamped on the front machined pad?

I would say 1973 model year, for sure. Maybe 1972, but it would have been the end right before the strike.
