That's the stuff!!! Thanks!!
I actually didn't order the registration codes as my uncle didn't remember what his was....but he did remember his bumper codes and I ordered those instead as they had the stenciled version available.
I have a new favorite decal company! My only complaint is that the pics of the decal sheets are too small to see what they offer. For instance, on the hood of the GMC 6X6's were in letters "Prestone 44" or whatever the appropriate year that denoted when the antifreeze was added. I was looking for a decal of that if available-- but the decal sheets that might've provided this were too small to gaze at.
I'll have to look through each of their downloadable catalog pages to see if they are bigger there.....
Thanks again shermanfreak-- I owe you one!
