Thanks guys, I appreciate the help.
My uncle wasn't much into doing anything in the way of customizing; I have not found anything else on the truck that was changed. I cannot say with certainty he would NOT have painted those letters but seems less likely. But as you can tell from the picture, someone did. Guess I am just going to leave them unpainted for now and if any solid evidence ever comes up, it can be done then.
Thanks, Joe
