I am looking for a seal that goes inside the break booster for a 1964 FORD F350.
I am not sure that it is the original booster but it may be. There is a shaft that slides
snugly through the center of this ring seal.

The inside diameter is 1 3/16 inches.
The outside diameter is 1 7/8 inches.on the smooth side.
The outside diameter is 2 inches.on the beveled side.

Here is a link to a picture of my seal.

Please let me know if you have one or where I can get it.

Thank you,

Arthur
