With the technology today there is no reason this couldn't be done. There are tons of these cars out there that look great until you open the hood and then it becomes a disappointment because the hood liner is ratty. I've gone to a few shows and seen some nice looking custom embroidered hood liners for these cars. You can still buy blank hood liner replacements with no lettering from GM as far as I know. Why can someone not reproduce the original lettering in a stick on or Velcro form to put on one of these? Embroidered hood liners could also be a possibility and would probably last longer and look better, but they wouldn't be like the originals.
