Hi Ron,
Previous owner here. The pin type are for the 1970 hood. The hoods heat up for obvious reasons and the tape was not a good method of applying the name badges. For 1971, tape was used on the fender badges, although the font and style of the letter is the same (as least as much as I can tell). I used the factory application instructions for the location, so where those badges are should be pretty close to correct.
Hope you are enjoying the car.
Chris
