Hello Folks,
After a one week wait, I just picked up a pair of the washers that go between the block and water housing. For those of you who do not want to wait a week and just make your own they are - .021 inch thick.
Good luck ~ JEB

 

Thanks for the info. You could have just made them out of gakset material. They are there to keep the housing even and flat. Gasket should do that equally well.

 

The pump to front plate gasket is thin to begin with. Then it gets crushed during waterpump installation. Try to use the same thickness material if you can. Maybe even one or two sheets of notebook paper (heh, I'm not sure exactly how thick that would be).
