For the bedbolts click on this link:

It should explain most any question you have about the tie down points. All you need is a 3/4" hole saw and a 1 1/16th socket or adjustable wrench to tighten them down.
For the wheel chocks, this is what I was talking about

I bought two removeable chocks and an extra mounting kit.
I don't have any pictures but let me try to explain how I installed mine. I anchored my chocks to a piece of plywood so they are completely removeable from the bed The plywood extends from the bulkhead of the bed back as far as you want. Just mount the chocks back far enough on the plywood so they clear the cover box. To limit side to side movement, I mounted the plywood board to a couple of two by fours that are the width of the bed.
By using this combination, I can put two small dirtbikes side by side or my big streetbike (Triumph Daytona 955i.) without any problems.
Any more questions just let me know.
