i broke one of my center ac vent trim pieces today installing my gauges could use some help finding a new one. any one have one laying around or know where i can get one.

 

ummm, which Firebird do you have?

 

That would probably help. It's a 02 t/a. Ws6

 

I got all the numbers 'cause you're gonna break them LOL:

17997683: Driver's side vent grill;
17997681: Center vent grill;
17997682: Passenger side vent grill.

These have fish hook like barbs on the outside ring. You'll need to shatter them to remove them without ripping the dash pad. Make sure no broken chips go into the ducting hoses.

Get the parts at Parts Taxi.
