Well I still have not ordered a skid plate for the tummy tuck. I did call Barnes and the way they explained it was the DIY skid plates ( which seem to be more popular) do allow you to drill and paint and decide which height you need. So you are supposed to
1. support your transmission,
2. remove the stock skid plate
3. measure how far down your transfer case is below the bottom frame of the jeep
4. determine how much higher you want the transfer case to sit.
5. order the right skid plate for your liking
6 mark the transfer case to skid plate bolts with lip stick, raise the skid plate into place, remove the skid, drill the holes according to the markings, install skid plate and nuts on the exposed bolts. ( they do have some kind of bolt/nut protector so ya wont rip off the nuts when going over rocks).
The other skid plate they have is more like the stock skid with a few improvements. I do think it raises the transmission about one inch but I will make sure about that before commit to that .
