Thanks for the return note. The shocks are new KYB AGX. My son installed
them, so I'll have the alignment shop check them out for proper installation and also general condition. The car is very unstable in the rear end. Its as
if the body were not connected to the frame. At speed, its actually
dangerous. My new mechanic seems to think its a combination of problems
with the camber/caster/ toe in or toe out. I'm hoping that its not a bent
frame. If it's not one of these systems, I can't think of what else it could be. I've replaced or fixed everything else in the car.

Anyway, I'll let you know what I find out - Thanks,

Doug
