use a tape measure. put the truck on stands. take the 20'z off. remove the shocks, bags, or whatever is it the way. find out what diameter the 24" tire is. measure the frame to the ground. add that to half the size of the 24. jack your spindle up until it binds or you reach that measurement. modify the suspension accordingly. if simple math is too hard, then back away from the truck.
