Good working condition. I have pictures and part numbers to identify correct parts.

I'm pretty sure I have on here. Came out of a 1980 sedan. I just need to double check that it holds vacuum ok.

The main difference is in the connection at the brake pedal. Early cars had a "fork"-like connection, later (1981-1984) cars had a single eyelet (like a needle).

Let me know if you still need one.

... and on the master cylinder side the master cylinder is expected to seal to the booster.

Later boosters had a space near the bottom of the hole for brake fluid to drain if the master cylinder started leaking.
They seal around the base of the shaft.

Early ones leaked right into the booster.
