Buldozer, I beleive you are right about not getting into the support with a 2" body lift. The only reason Chad had to cut more was because of the little nub that stick out the back of the shift tower, he ended up cutting approximately another inch out, so I guess and inch up is equal to an inch back with regard to the hole you cut. We installed his motor and tranny together and just couldn't get the motor mounts into the slots with the smaller hole.
