If he's willing to pay for NOS, then he may want to look into simply making his own. Simply repair the current parts, make a silicone mold, then cast the lenses with colored material designed for the project, and cast the metal parts out of whatever metals he can melt and plate. It's not as difficult as it sounds, and there is a member here who can direct you to the proper products to use (John, you reading this? ).

Also, the HUGE Old Car's swap meet in Iola, WI is this coming week-end. If those parts aren't there, they aren't anywhere! See if you can have a local member who is going look for them for you!
