What does the decal look like. I did that model a long time ago. I do remember that the real Bullit Mustangs (there were several used in the movie) had all of the "badging" removed, e.g. the M-U-S-T-A-N-G letters across the trunk, the grill Mustang symbol, GT badges, etc. In fact the grill had a screen cover over it to cover the holes for the driving lights. Also note that the "Highland Green Metalic" paint is a stock Ford paint for 67/68 and is available from "Model Car World Automotive Finishes". See their web site. Google 1968 Bullit Mustang and you should find a plethora of "Bullit Mustang" information.
