I know this is a pretty old thread but I wanted to revisit it due to my own interest.
I’m having a heck of a time tracking down the specific part and I was hoping for some more clues.
From what I have read a 1982 Charger is just a Plymouth Horizon or a Dodge Omni with new badges. (trim package)
The cylinder for those doesn’t look anything like the one I have. Is that normal? Is it this one?
My master cylinder has the two brake lines as well as a tap on the opposite side for electrical. A low brake fluid sensor in the tank and one directly into the cylinder for something else. Does your suggestion take those into account or am I just looking at the wrong part?
