I will be adding numbers to my non-heritage GT. Can someone please take measurements of the diameter of each circle and the width of the black outline. Also, if you have the number '1', can you please measure the heigth and width of each one. Thank you so much! I will be having a local sign shop do these for me for $118 instead of $3000 from the dealer.:eek I know this question was asked before in another thread but it was never answered. TIA!
