I replaced my front filler panel about 15 yrs ago,with an nos piece. It started cracking last year. At Gettysburg it cracked everywhere,maybe heat. I looked at a 74 with the fiberglass filler,there in show. Looked good at each end.In middle it sat back about ,.1875 (3/16)to .250(1/4) inch.So it needs work if you use it. Ames still has filler pieces listed should I get another nos type or modify fiberglass one?Another guy had replaced his with nos piece but hasnt had cracking. Is there a process to stop this cracking on nos pieces?
