Ok, here ya go 400droptopbird : the top /bottom lines are 1/4", and the middle line & the HO are 3/4". The dots for the HO are also 1/4. The stripes are about 1" from the wheel trim( notice how the line follows the well curve). Hope that helps. Not sure what ya have in mind, but I got mine from Classic, 3M top quality, however I did find them cheaper by digging around, just can't remember where...anyway, if you have come this far, no time to scrimp now....like they say, you get what you pay for! Good luck, would like to see it when your done, Kel 68 Blackbird
