Hand made one of these for my personal car and had some interest in them, so I made a template and now get them laser cut. It's saved my apron from total annihilation on more than one occasion. These fit any type I, BJ or LP. Only hangs down 3/16" and will help you skip over obstacles, landmines, roadkill, curbs, jumps, bumps and lumps! No modifications required. I do suggest cranking up or removing the lower vertical adjuster bolt. This will provide some armor for your panhead and in most cases, saves your apron and wheel well from a bit of damage too. This will fit any type I with a front beam, 38-77. Please specify Linkpin or Balljoint as I do bend them a bit differently for each, for the best fit. These bolt to your front axle beam, with the bottom two bolts. No longer bolts needed. 3/16 plate, Hand bent by me and fitted to a beam before shipment. $60 shipped anywhere in the continental US!
