Default Master Cylinder Top

While cleaning my engine bay, the cap to my master cylinder flew off and went into the engine bay. Unfortunately, I was not able to find it. I called 2 dealerships to see if I can buy another one but they both told me it's on back order and they don't know when they're going to get more. Does anyone know where I could possibly get one from? I live in Maryland.

Thanks
Jim

Check with a local parts store like auto zone. Dorman makes replacement caps complete with DOT3 emblem

Thanks. I just went to Auto Zone and bought one. It fits, however its pretty loose. On the back of the package it indicates to replace a gasket as well if the old one is worn?

You may have to fab a gasket... no problem, but you want the lid to fit tight.... Chasing parts just like the old days. 😏

Well it appears I also needed the gasket as well. So now it fits snug. For reference it was Dorman part # 42042 and 42072. Appreciate everyone's help!

Did you remove the panel in the drivers side wheel well? That’d be my guess for where it went

I didn’t think of that. Thanks for the suggestion!

A little late now unless you really want an OEM cap, but you could check with Vettenuts, a forum vendor who specializes in used parts.

Since I've already installed the cap from Auto Zone, I'm inclined to leave the original "lost" in the fender. I did have another question. I noticed that the body or white portion of the master cylinder appeared to be a little loose. Anyone know how to tighten it?
