Always found Classic Industries to be helpful.

Well, they have seat covers, but a lot of the little plastic interior
stuff isn't there. I hate having to do a hit and miss at a boneyard
to get that stuff, it would be great to order it all and have it show
up in a big box.
Try your local Chevy dealer. There maybe parts still available. Take
the VIN # and the list of parts with you. Google firebird seat
covers. There is one online company (don;t have the adress) that will
take them for around $ 800. My local interior guy (been in the
business 50 years) gave me an estimate of $ 1600 to hand make the
cover out of OEM.
Keep googling and calling. Check local papers, auto locator type
papers for folks parting out f-bodies. Also Hemmings Motor
(HemmingMotor.com?)
Good luck!. Don't let it get you down.
