My headliner needs to be redone on my car, but i would like to make a little customization... I've seen how to do headliner custom ideas using a headliner board, 1/4 in. thick foam and some material to form whatever you want ex. Flames.. I see that the first gens use headliner bows is there anyway to either switch it to a headliner board or if that's not possible to customize my interior, i was going to have the firebird symbol and the word firebird underneath it....
