70 duster street strip build

The first is From the outer lip of the quarter panel and reads little over 2 inches and the second pic is from the frame rail to the back of the rim and reads 3 1/4

Thank you. That helps a little, but you are using 10.5s now with 315s correct? Do you think when you get some free time you could do similar measurements but from the sidewalls of the tires?
