I don't think you "Bungled". Either that, or we both did. I've taken this on and off so much now, i really can't see another way i could mount this. I'm wondering if different year trucks possibly have the holes drilled in different parts of the frame? I wouldn't imagine the wing mount brackets could be drilled wrong. Anyways, end of last week i went in determined it'd be an easy fix and that all i needed to do was move the wing brackets down to the 2 lowest holes. After completely taking the wing brackets off, and loosening up all the hitch bolts for play, the holes in the frame did not match up with the holes in the wing brackets. i tried switching the left and right bracket, that didn't work as the passenger bracket then hits the plastic fender molding so you cant even line up the holes.
So, after a few frustrating hours i thought, well, Maybe the master bolt count man
@grinchy was onto something. if i have a hole big enough to fit a huge 4" x 5/8" bolt, how could this not be better to use it than 2 smaller bolts? Bigger is more better no? So, i used the large hole for the 5/8", smaller hole for 3/8", and just did a workaround. As some had originally mentioned the spacer idea, i put my wing brackets mounted up at the top edge of frame like i had them. I them went and bought four 3/8" x 2.5" (i think) M8 bolts, nuts, washers, and lock washers. The key was then Ace had these perfect fitting 1" tall stainless bushings (with 3/8" holes in them) to use in the middle as spacers. Now i wont say these were east in any way to jam a 1" spacer in there, but eventually i got them all in with a crowbar to flex apart the bracket from bumper, and a very important magnet to hold the nut to get the threads to catch eventually.
End result, as high and tight as it could be mounted, as level as could be. I'm happy with it. Just thought I'd post in case anybody else runs into this same wing bracket hole/lineup mounting problem
spacing i ended up with about 5.25" up front, about 9.25" in the rear. My plastic is now completely NOT cut correct. But whatever for now, and maybe I'll find a salvage bumper cover in the future to re-trim.
