i am trying to find a replacement for this dust cover that goes over what i -think- is the cruise control motor/servo. do any of you have a part number for this, or at least the proper name for it so i can try to find a replacement? hoping i can find one without dumpster diving in junk yards... car is a 1997 LT1 Z28 coupe,

 

That is the TRACTION CONTROL (ASR) servo. Replacement may be hard to find, because ASR was optional , so not installed on all cars.

Have you removed it and looked underneath to see if there is a part #?
