I wouldn't ask you to turn anything....because the truth is that this "spacer" is never actually going to rotate.
What I really want is a 1.5" plate that has three holes for the studs on the stock tire carrier, and another three holes with studs pressed into them, to allow me to move my spare 1.5" further away from the tailgate than it currently is. That will get it off of my VHF and CB antennas, and make it a lot less irritating for me to put my spare onto the carrier. Even my very meager fab skills would be enough to make this item....if I had a press, a drill press, some 1/2" plate, a plasma cutter, and a welder.
Or I could just wait until someone has a beat-up old Spidertrax 5 on 5 spacer that they're willing to sell me for $25 and use that.
