This Support swap started a couple years ago. Its since been finished for awhile but I never posted pics of the installed part. The swap consisted of drilling most the spot welds from a decent light duty RS and the HD RS and swapping the mounts. The Rad spacer had to be made so the straight six rad would fit in the larger opening. The only other modification was drilling the holes for the inner fender mounts. The dimples for the holes were there is was just a matter of drilling them.
