Exact match for a 60 year old part.
Exactly the same unit as was on my 60 year old truck, and functions perfectly, thanks.

Solid, and identical to the old one it's replacing ...
Solid, and identical to the old one it's replacing. Only hiccup is the clutch side cylinder returns slowly (3-4 seconds instead of 1 second on the other one) during the bench bleed... hopefully no big deal.

Defective...hope second one is better
I bought this for my Dad's 1962 Chevy. It was defective and had to be returned. Hopefully the second one from Amazon is better. We'll see in a couple days. The first one had a problem with the brake side piston. When attempting to bleed the master cylinder per the instructions, the brake side cylinder would get stuck and not return properly. The clutch side piston was fine.
