The seat covering is worn through and the frame bent on my firebird front seats.

I'm having difficulty locating third-gen or fourth-gen seats in nice condition at the local wrecking yard. Located a couple Pontiac GrandAms with very nice front seats.

Dimensions of Pontiac GrandAM front seats appear similar to firebird seats.

Will a grandam front seats bolt onto the firebird seat tracks?

 

Yup....

 

Where are you located, and what year is your Firebird? Someone here that is close to you might be able to help you out with finding the correct seats for your car.
