As I have been gathering parts for the restoration on my '70 GTX I checked on the condition of the die cast "PLYMOUTH" letters that go on the tail panel of the car, they are not in real good shape, so I decided to start looking for NOS replacements. As I've been looking I see that some of the letters are blacked out on the inside, leaving a chrome outline of the letter with a black inside, and some of them are just chrome with no blackout detail. The part numbers for mine are 2528974 - 2528981, each letter has a different part number. I've seen both the blackout versions and the all chrome versions using the same part numbers, so I'm thinking to myself, what gives? At first I though that some people were painting the insides of the letters because they thought it looked better that way, but I see that even the NOS ones are the same, some blacked out some not. So, I figure I'd start looking at pictures of '70 GTX tail panels, but I can't really find any pictures that are good enough quality to show me the letter details. So, does anyone have any insight on why the different letters? What applications? Which years used which? I think the letters on the '70 GTX are supposed to be the all chrome versions but I don't know that to be absolute fact, any input?
