1965 Dodge Dart Charger

I have seen the white foam gasket on several cars but this special gasket between the brake booster and the master cylinder is the first of it's kind I ever seen.

This is the answer I got from the Ram man.

"the early bendix..the sole purpose of the gasket was a spacer for the master cylinder piston retainer screw on the back of master cylinder was not considered a part to ever wear out..non serviceable...reuse old one.period

have not seen fiber gasket in over 20 years"

I guess I need to get a better used gasket or reuse my old one.

Any NOS ones out there?
