I use the body line on the truck as a reference point, to calculate the lift , I run 8" of lift in the frt. & 10" in the rear, I just put this lift in, I had 4" lift springs & 6" of block in the rear. I ran 35's but now I've got 37's. A word of caution... run some kind of traction bar with that much block, torque is multiplyed with blocks, I tore a rear end off with less block than that, on another truck.

4'' springs in the front should do the trick

My 79 only had a 3" lift and 35's fit it good. It looked better after the 2" body lift, but they will fit w/just a 3" suspension lift.
