The linked post photos all appear to be ones I have filed away from the net and added to that post
Cuda Hunter the Yellow ebay car neither shows a V21 or G36 code. Tag appeared full we'd need to see the build sheet. Notice there's no EN2 shown on the tag, and the V21 would have been right after the R11. (Edit I was missing the word "no" and the last code at top right as EN2 indicates end of codes assembly line 2)
The painted grille is not a V21 thing but was coupled with the G36 painted mirror option, if the car was a Cuda in certain specified colors.
According to the tag it was a G37 Chrome mirror car.
If I'm not mistaken it's missing a 2nd data tag note the attached hemi Cuda tags, I believe the last code indicates the next tag....
