Master cylinder gaskets (62)

[Ed Jennings]

One thing I did not get away with when I rebuilt my MC is reusing the copper crush washers on the outlet block. They are GM 799390 and GM 799303. I assume I can pick these up at a parts store if I know the correct size. Can anyone help? Joe, if you can do this one, I won't bother you about fuel pump numbers for at least a month! (well, maybe 2 weeks anyway)

The GM #799303 copper washer is 1/2" ID and 13/16" OD

The GM #799390 copper washer is 19/32" ID and 13/16" OD

Addendum

By the way, the GM #799390 washer is still available from GM for $1.85/each. The GM #799303 is discontinued, though.
