Update: Drove the 53 to the inspection station today. Had an hour to get there before they closed. Stopped for gas a few blocks away so that I could be sure that I wouldn't run out before, during or after the inspection. Everything checked out...except for one small detail: no mud flaps!
Mud flaps!!
Wasn't even on my checklist. And they can't be just any old mud flaps. They have to be at least as wide as the overall width of the dual rear tires and come within 8 inches of the ground.
I called my trusty AC Delco parts store and their biggest flaps are 24" x 36". I did some measuring and I think those will fit like a glove. Of course it will take some fabricating since the truck doesn't have any existing brackets or anything.
So...off to get the flaps during my lunch hour tomorrow (Friday). I'll work on getting them installed after work and have to take it back in Saturday morning for Round 2.
Fingers crossed, everyone!
