On OEM HEI's, there is the thrust washer w/tangs against the distributor. Then a shim. Then the gear. If the end play was set, usually there will be several shims or possibly a thick shim to replace the ~0.015" shim that the dist. comes with.

As long as the dist. isn't bottomed out, there's a fairly wide leeway for where the mesh occurs on the gear itself, w/no adverse results. The pattern has to be all on the gear, not running off the top or bottom.
