Does he have an air bag or coil over rear suspension set up? If not, using an MII ifs is only half the job unless one likes the potato digger rake angle. A couple of pics showing a 55.2 with MII and stock rear leaf springs and another showing a 49 that has rear coil overs to bring the rear down to near level with the front. Whole truck sits low. I have a pictorial on frame brackets to make an AD sit at factory height with an MII ifs if interested.
