I have an 88tII and just replaced my springs,shocks and struts. Now on my rear left spindle there is a bushing that the bolt goes through to support the bolt. The bushing is no good and all chewed up but I can't buy just the bushing the dealership says I have to buy the whole damn spindle.The bushing is inside the spindle itself.

 

Have you checked Mazdatrix's catalog to see if they sell just the bushing?
