I need some measurements

Yep. I have an all original 66 100 model. Do you have a photo of what you want?
My lid doesn't have the holes for the letters I want to install. I just need to know where to drill the holes. The best way would be a sheet of paper taped to a bare lid and holes punched in the paper where the emblem holes are. Next best would be exact measurements from the body line down to the top of the emblems and measurements from the edge on one side to each emblem in turn to the other side.
