After the removal, I did a quick overall inspection and noted that I had a couple slight leaks. I picked up the parts to address them at a later time. I then thoroughly washed the under body area covered by the old skid plate.
The new skids arrived strapped and screwed to some cardboard and wood frame packaging. The spacers for use on kits without a diff drop were kicking around loose in the UPS truck, and several of the screws were bent and loose. Of course, that didn't phase the plates.
I removed the parts and set them out on the floor as they would be assembled. I set out the contents of the hardware kit:
IIRC, no pic.
4- square aluminum plates with threaded inserts and corresponding threaded bolts.
7- 8mmx1.25 threaded bolts with corresponding flush mount counter sink aluminum washers.
8- 8x1.25 bolts 13mm head
12- washers
Then I set the rear plate aside and drove my truck in over the plates to aid in placement.
I realized that the rear mounting holes did not have threads and figured that the only female threaded hardware plates would go there. Sure enough the rear holes needed to be drilled out, but a step bit didn't work for me, cause the bit would hit the frame inside the hole. I resorted to and 11/16 drill bit to make the holes big enough to fit the plates in. it was still a tight fit, so I clearanced one side of the 2 rear square plates just a bit.
I ran an 8x1.25 tap through the 5 threaded holes on the main cross member, and the 2 holes on the diff drop cross member. These are the 7 holes for the 5mm allen flat head bolts. I found a floor dolly kicking around that was a perfect fit for installing these plates. I used a 2x and a 4x to position them around.
I added anti seize to all of the bolts. After getting the rear 4 bolts started, I hung the middle plate on the forward hook and supported it with the dolly. then I started the bolts and washers in the main cross member.
