Someone else just went thru this. The copper rings appear to no longer be available from any of the sources.

The rings are very thin and ordinary copper sealing washers readily available are too thick. With todays improved sealants it is debatable if the rings are still needed. I would omit the copper rings but add a relatively thick layer of one of the oil resistant RTVs to the base of the studs right at the gasket so that material is able to work into the space between the studs and carrier holes to fill any gaps just as the rings did.

The mechanic working on the car may have a better suggestion or possibly knows of a GM substitute for the rings.
