I found the TSB that has the updated swaybar bushings for the rear swaybar. It reads as follows:

Subject: Rear Suspension Squawking Noise.
Model & Year: 1982-85 Camaro
Bulletin Number: 85-60
Section: 3D
Date: March 1985
Condition: Squaking noise from rear swaybar.
Cause: Dry Bushings.
Correction: Install new swaybar bushings with a Teflon liner. Position new bushings with the slit to the rear of the swaybar.

Parts: Z-28 #10037104 Bar dia. 23mm (.906")
FE2 #10037105 24mm (.945")

This bulletin dose not cover Camaros with the F-41 swaybar 18mm (.708").

I ordered a set and installed them. I think the cost was around $25. I went to a shoping mall on a cold day (45 deg.) and drove over some good sized speed bumps. The front (still trying to find TSB) swaybar squawked like crazy but the rear made no noise at all!!! This was a cheap and easy fix. I hope this helps some of you guys in the colder states.
