Dan,
I have not found the original style master yet that I’m trying to replace.
Even NAPA and the other auto stores don’t even carry this original style anymore.
NAPA’s offering is identical to the newer AC Delco replacement with the same stamping China made.
Their web site/computer photos have not been updated and show the older double bail style but when you open the box it has been replaced with the newer single bail resevoir.
Frustrating and shame on AC Delco
I can’t understand that a replacement or rebuilt older style part is not available.
What style is your C20 master cylinder?
1” deep bore?
Part number and photos would be appreciated.
Thanks for your response
