BillyDon, a couple of years ago I made a GPS speedometer for my 1952 which looks pretty much like the original. This question has come up enough lately I'm considering making my next "project" a GPS speedometer that will fit right in and replace the original speedometer so the speedometer will be accurate no matter what. You can see what I made below. (I did add right/left turn signal dots, but those can be omitted if desired)
