5468309 Master Cylinder with no Stamp?

**72-SS-L48** · #1 03-03-2023, 01:00 AM

I think the applicable is 67-69 Chevelle/ Nova/ Camaro? But no BA, GA or EA stamp on the machined surface. Still a factory part or service part?

Thanks,
Dave

I suspect it was stamped lightly, and the code was obscured by the rust. My WT master is stamped with such little force that it’s tough to see the code.

The master on my 69 Chevelle has no rust or pitting on it at all, and I can't see any stamp on it either, even with a magnifying glass and ample lighting.

Are my eyes playing tricks or is that US stamped? Worst case chuck up the master in a mill and use a 4 flute end mill and buzz it and restamp.

I don’t see it but not doubting it’s possible.

Def not going to restamp. Not my cup of tea

----Good! Add to that, you would have to face the other two Machined pads as well to make it look uniform. Slippery slope for sure! I think I would dip that thing and get it good and clean of debris so you can see what you have to deal with.....Bill S
