Now lets install the wood. Start from the outsides, slide under the edge strips, line up mounting bolts, blocks, rubber pads and frame holes....easier said than done.... Lay in the next board, this one has the front mounting bolt.... That has to go through the sill, the block, the rubber, the top, middle and bottom of the frame. One lined up fairly well with a large Phillips head screwdriver through the whole shebang, the other required another person to whack it while I was under the truck "influencing" it with a prybar to go into the bottom frame hole. Much swearing was involved. Be shure to seperate them properly with the stainless strips... Each hole gets a carriage bolt, LARGE washer, lock washer and nut. You can place them fairly easily by yourself as you go by standing in the bed hole, but as you run out of room, you need someone to hold them from up top and someone to run the nuts from down below. To get into the cross sills at the top, middle and back, after a few lock washers to the cranium, I devised a plan. I used a flexible nut driver with a standard socket on the end. Fill it with nuts, then put a little weatherstriping cement on the lock washer to hold it in place, stick it up there and start it. Repeat until all holes are filled.
