Well I thought I would give these a shot on my gravel driveway. Not sure how they will work but only one way to find out! I took the stock shoes and added approx. another 6" to the length. Then I made a set using 13"x 5" x 3/8" hot rolled. Next I welded an angle on the front edge. Then took another piece of plate 1/4" thick by 6 1/2" x 5" milled adjuster slots and then welded them together. My first weld job as you can see!!!! I didn't put a rear angle on because I wasn't sure if I had clearance. I will probably will add it but I thought I would see how they work first. They may float to much, thats why I revised my other set in case these don't work.
