trying to get back my 67 GMC front end!!

[Dzznuts]

I'm having some troubles figuring out what I need to change my truck back to what it is.. 67 GMC, not Chevy...
I mistakenly changed it when building to save money and moved across country and now don't have any of the parts..
I know I need 67-68 core support , center support, 67 grille, but I've seen some grille's that have the upper support attached.. Is it only grille with GMC letters on it that will be right? Also light buckets... Are they same from a 67 to later? Brothers trucks sells them as many years fitting. I'm alittle confused and frustrated I didn't keep that stuff 😈
