I bought a 67 tub with what looks to be factory holes for lights in the rear tailight section, right in the middle on both sides,. I once saw a halfcab with them, they were round, clear globes like on the the older pickups with a chrome ring. I've searched high and low for any info but never came across. Makes me wonder now that this is the second 67. These were on the sides, not under the tailight lense, be cool if they were a rare addon.
