That isn't the problem. (My title was wrong BTW.) The larger sheet that attaches towards the back of the bike has two holes to insert the screws. The Bolts are welded to the aluminum sheets. After several tightening and losening the screw from the nut, the nut detaches from the aluminum sheet, rendering the forward piece unusable.
I don't know how to repair, so instead I am going to get the belly pan that has the aircraft fasteners.
