I' am going to replace the sagging headliner in my 97 firebird. I can't figure out what color my headliner is. It is either very dark gray or medium dark pewter. The rpo code says that is has the lt. gray interior group with lt. gray leather.

 

Are You Doing The Replacement Yourself Or Are You Have A Upholstery Shop Do It? I Bet If You Went By Your Local Upholstery Shop They Could Look It Up Or Match It For You And Sell You The Few Yards Of Material.
From Experience I Have Learned That For The Money It Alot Easier Having A Shop Do It For You. Hope I Helped
