This late panhead/early Shovelhead swing arm is for sale. It is an easy and good looking swap for later shovelheads. I believe it lowers the bike 2-3" from the square swing arm. I had this on my orange shovel before I hard tailed it. It comes with the axle, spacers, and late model harley caliper which I modified to run with this setup. I also welded mounts to it for a fender and sissy bar so they would hug the tire on a swing arm bike.
