My passenger side inner fender had no captive nuts. It just had square holes I assumed to be for carriage bolts. Between the cab and inner fender were about 4 thick shims for each bolt. Again with the assumptions, I thought that these shims were in lou of the proper bracket which I thought to resemble that of the drivers side. I knew something was up cause with no captive nuts assembly requires a helper monkey to hold a wrench outside while you turn a ratchet from the inside. A pic of just what is supposed to be going on would be great. I am going to have it on and off quite a lot as a reference for remaking the front lower cab sheet metals.
