I think I understand the question.
Go here and look at the very bottom left hand side photo of the driverside cab. At the bottom front of the cab just at the front of the door bottom, and step/ rocker panel is a little bracket with a hole in it. And yes the fender should have a caged nut for the bolt that runs through that hole. To adjust the fender to be even with the door you add shims between that bracket and fender.

If you click on the photo it makes it bigger.
