I'm having a hard time finding the correct front stablizer bar insulators for my '89 GTA. I went to three different dealers, but they don't fit. The hole size is correct at 35.5mm (I have the 36mm front stablizer bar) but the insulator bushing itself seems to be taller than the original bushing and won't allow the swaybar bracket to fit flush against the frame rail support. I even tried Moog aftermarket, but they won't fit either.

Either there's a major screw up in part #'s for these particular bushings or they have been discontinued. However, why would both the GM and Moog versions not fit if that's what the computer listing calls for?

 

The small 35's will work from ES. here's the spec chart and part #. Cross reference them to Summit racings ES #'s and you can order them through Summit.
