upper control arm bushing notch's?

Bite, yeah thats it.
Have you considered the problem solver offset bushings? I highly recommend them.Our A-bodies need all the caster you can find.

Couldnt think of what to say those notches did.. Bite was the only thing that came to mind LOL.

I agree that the offset bushings are a nice upgrade but not necessarily needed. Lots of folks on here running just the standard bushings and lots running the offset bushings. I would say the more performance tuned cars, or people that like to corner should use the offset bushings. If your not a aggressive driver and just casual driving then the standard bushings would be enough.. Do you agree?
