Manual disc brake master cylinder?

It says that but is actually not a good replacement - esp for '73
That's the drum brake master they remove the valve from the rear outlet and call it good enough. :(

If that is the case, then don't buy it. I thought the cover may just be symmetrical over 2 different sized reservoirs but get the actual big/little reservoir model. My oversight on believing their applications.

maybe this one>...Raybestos MC36412. Just has pics. specs over to a 76 Volare
