Where to get headlight linkages?
 

I need the linkages that connect the headlight motors to the doors. This is for an 83 RX7. The linkages about six(?) inches long. They have a plastic bushing that connects to ball at each end of the rod. My bushings are shot. Can you get just the bushings? My rods are fine. I'm looking for a source for these linkages. Any ideas? The dealer can order them but they are expensive.

Thanks
