Brad, here's some pics for you. The uhmw is attached with 5/16" elevator bolts and the locknuts are countersunk. The stainless is through bolted with 1/4" bolts. Despite the way better traction I found the cleats to make the track more ridged and a lot less chance of running out of them if a tire loses air pressure. I also attached a picture of the drill bit needed to go through the rubber.
