Working on a 66 C10 with Western Chassis 2.5 inch drop spindles and 4 inch rear drop springs.

I went to the Summitt Racing website where have you take measurements of numerous positions for both front and back.

Trying to decifer how to use these measurements when specing out wheels and tires. I really would like to use 20x10 in the rear but only assuming 20x8.5 in the front. Bolt pattern is 5x5
