All the Original cars I've seen have stickers on the Support Gussets that these panels mount to. Typically one Caution Hot Radiator sticker on the passenger side one and on California cars an A.I.R. sticker on the other one.

Many have felt the radiator sticker would fit well on these panels, but I've never seen an original one there... nor any sticker? Maybe it was a Hooker Headers, or Edelbrock sticker?

I have pix if you want of the original stickers I mentioned?

Brett!
