Up for sale is a rebuilt 309 Disc brake master cylinder for a 1969 Pontiac GTO/LeMans
I thought originally the date was a Julian date "04" but now I think it is a upside down "70"
if anyone can shed some light on the stamp please let me know.
The "EA" is a light stamp like so many of the application stamps.
$ 285 plus shipping.
I will always trade up/down for Factory "US" stamped 309 Master cylinders Julian dated 30-90
I also have for sale another rebuilt 309 "120" dated "US" master cylinder that is too late for my cars.
Thank you SYC/ Charley!
