Hawks has them listed as 82-84, but my 86 has them....

 

my seats look way diffrent i have moving headrests and all that fun stuff and i own a 85 trans am

 

Those might be the "basic" Firebird seats, or most likely early Camaro seats

 

I have those seat (black) in my 1985 base firebird. I know that these seats are original to the car because its been in my family since it was new. Hope that can be some help to you. I know that this isn't the BEST picture but it's the only one that u have right here. Look at the pleats/ headrest on the seats. They are the same. -Bob

 

Thanks for the pic!
