67 Plymouth barracuda trunk trim “Barracuda” emblem

One difference is that the fender script has a long tail on the final "a" — the trunk script has a short tail. The other is that the fender script has long pins to go through the sheet metal with nuts on the back side — the trunk trim script has short peened rivets on the back — it is not meant to come off. I strongly suspect that the pins are not located in the same place on the back of these two scripts. I don't believe anyone reproduces the trunk trim script (or the panel, for that matter). Your best bet may be to haunt eBay for a messed-up panel that you can salvage the script from.
