I have a 309 brake master cylinder that has a "EA" code stamped on the nose instead of "US". Anybody have an idea what this came off of?

92646,

Check out this ebay item #. Then send an email to the fellow who sold this "EA" Mast. Cyl. He was very helpful and appeared knowledgeable to me. I am buying a correct one for my Chevelle.

I think the 1969 Chevrolet Chassis Service Manual, Section 5, Brakes, has a table (figure) Called "Brake Main Cylinder Identification" In it, it lists the main cylinder Letter code and model applications and other info. I do not have a copy of the 1969 issue. Others may.
Just a thought. http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif
