so i have a 1967 dart and i want to change the "D" to an "F" so it'll read fart.... i heard that the F's from i believe a 60's ford falcon are the same size and font and design etc. i was wondering if anyone knows the exact year or era type of car i should be looking for as i've bought a few F's that look similar but when i get them next to the car they are quite different.
