Hi folks, I replaced the master cylinder on the truck I am restoring and low and behold I have a leak at the copper gaskets that seal the bolt and distribution block to the master cylinder body. I was wondering if anyone new the exact dimension of those gaskets. There is a front and a rear gasket for the bolt and they are different sizes. I know I was shorted one in my order and I used what I had in my shop which I thought was very close to the size. Anyway I don’t want to mess around anymore and I want to see if I can purchase the exact size that is called for.

I had the same problem w/my '52 F1 . I took the copper gaskets/washers to my local parts store and got a couple new ones , plus a couple spares . Make sure the surface on the block is really clean! - F F

Some people have better luck after annealing the washers prior to using them.
