SS Barracuda front Bumper

So, anyhow, back on topic... I just had a thought (don't worry, I'm OK). Mind you, I have no idea in regards to what was done and won't assert anything a'tall, but:

If the outer bumper brackets were deleted, who's to say they didn't put a short bumper bolt in the hole to give it a finished look? That's exactly what I did when I was 17 after pulling the buck teeth off my '73 Challenger (front bumper guards). The holes looked terrible and it was an easy solution. I don't think looking for the presence of face bar bolts would be conclusive.
