Alright, here we go:
Radiator skid:
2 bolts and 2 nutserts, one on each side of the radiator.

2 bolts at the back of the radiator skid, bolted directly to the engine skid into threaded holes.

The engine skid has 4 big bolts, which go into the cross members (no nutserts as I recall). Since you have these bolts, I didn't snap pics. The front bolts are in those holes you see behind the radiator skid in the previous pic.
The front of the transmission skid uses the rear 2 bolts of the engine skid. The trans skid slides in under the engine skid so it will not catch on any rocks that are sliding front-to-back under your Jeep.

The rear of the transmission skid has 2 bolts, with nutserts, into the crossmember. The front of the transfer case skid is the same, adjacent.

The other two bolts of the TC skid are to the driver's side "frame", again with nutserts iirc.

The nutsert holes are hexagonal in shape before you install them. That's why it doesn't look like you could screw any bolts in there. Crawl under and locate the mounting points to check the number of nutserts you might need. It has been long enough that I am only about 90% sure about which bolts needed them, above.
Hope this helps, Gage!
