Some relevant info on these grilles:
After doing some research, I have found these original Chevy 1969-70 GM part numbers, and when they were superseded with the final part numbers that lasted the entire run. 1969-70 Steel black painted headlight bezels: 3937473 LH changed to 3990705 in 8/1971 3937474 RH changed to 3990706 in 12/1971 1969-70 Outer grille shell: 3980036 changed to 3985054 in 6/1971 1969 Inner grille: 3980037 changed to 3985056 in 8/1971 The likelihood of coming across these NOS parts 50 years later is slim, but I just purchased the original steel headlight bezels, so they are out there. I would imagine that the 3980036 grille has the black painted strips that run the entire width of the center grille bar versus the 3985054 GM replacement and all of the reproductions. Its very easy to see which trucks still have their original grille shells.
