GMC Tailgate Panel grille

[jlmerie]

I have been looking for a really nice GMC tailgate panel for my 1978 truck. I thought I had found the holy grail when I came across this panel. It is in amazing condition. The plastic GMC emblem is broken, but that did not bother me because I have a correct metal one for 1978. When I start looking more closely at this I see the pre 1980 panels are different than the later ones. I thought the emblem was the only difference, but where the panel is drilled for the emblem studs is different. Are there other differences from the early and later style panels? I am beginning to think I am not going to get this one to work right and I am back searching.
