quick question on stretch length

[SuperDutyScaler]

in post #4 can you see the two holes right in front of my yellow shock? there for a third axle that joe drilled out on the frame. Luckly they are the same height as the shock holes so i was thinking about using the first hole for the half mud flap, the second hole for the shock and then just drilling new holes for the rear axle mount and cutting the rear of the frame two inches to shorten the truck up alittle? plus it will make building an new driveshaft easier, cus this sucks not be able to run my rig now that its stretched.
