Yes, a 1979 Firebird tail light will fit a 1979 Trans Am. There are also restoration services if you have the tail lights and they just need to be repaired.
Check the Firebird and Camaro seats.
Yes.
no it will not fit
Yes
yes they do
no. but it will fit on a garbage truck
I have not found anything that would indicate they they are interchangable
Yes...it absolutely will. In fact, you can change them all from 1970-1981 if you have all the parts from the front end to do it.
Grille only....no. Complete front fascia....yes.
Bolt on... no. With a little modification... sort of.
As far as a direct fit, the 82-92 Firebird/Camaro is the same generation. Any from these years should be a direct bolt in.
All Camaro and Firebird/Trans Am T-Tops from 93-02 will interchange.
