Lee, According to the assembly manual frame width 60-62 at rear frame end 41.72", 63-66 is 41.82". Not much difference. Putting the tape to my frame (61) I get 41.75". The bumper brackets are bolted to the frame rails and are set outward 14" for the outer mount hole and straight behind the frame rail for the inner. The mounting holes in the brackets are slotted .75" for adjustment R to L. The ends of the brackets are 9" behind the frame rail end at the top corner of the inner bracket. Center of mounting holes on each bracket is 14". I'm thinking the fit of the bumper is all determined by which brackets you use, provided your rear frame width is the same, or within .75 inches, of the later trucks. [IMG]Jan12232[/IMG]
