I have Snap-On's Shop Key program with the TSB you need. The problem is it wont let me cut and paste the info. This is all I could type for now. I* hope this helps.

1993- 1996 Camaro / Firebird
Section: 4 - Drive axle
Bulletin# 67-41-01
March, 1996 Affects only vehicles with 5.7L LT1

Some owners may experience a vehicle vibration at highway speeds. When measured at the drivers seat track, this vibration will be a 1st order driveline frequency. The same vibration can be confirmed at the axle pinion nose and at the rear extension housing of the transmission.

CAUSE: First order drive line vibration may be caused by beaming between the engine and transmission.

Correction: A previously released propeller shaft is available to address the highway speed vibration condition. Verify condition per above note that the vibration is 1st order drive line disturbance; preferably using an Electronic Vibration Analyser. (EVA) Other conditions such as excessive drive line anglr difference may produce 2nd order drive line vibration concerns. The proper procedures to measure and correct for excessive drive line angle condition are not shown in the current Service Manual. Consult a 1992 Service Manual for the proper procedure. The front and rear propeller shaft angle must be less than 1 degree of each other.

Thank you! I doubt they will still honor it, but at least I know what the problem is and what I need to correct it.
