OK so here it is, my apologies if this sucks but I'll try and explain. So the mount is a sliding mount. Two strong steel "u" shaped peices are welded to the frame in the proper positions, thus providing supports for our sliding plate. In hindsight of my own I would just use two long rails instead of the way pictured. The grey parts illustrate the three bolt setup. One is the "lock down" (Circled in green) Bolt, should be of large diameter and good grade. The other two are the clockable or slide adjust bolts(circled in blue)and should also be high grade. My original one has a small mount I have made(labeled 1), but I find it a challenge to get a tool in there. My new design is going to have two holes drilled through the front downtube and additional support bungs be put in place(labeled2). Notice the offset when looking at the front of the plate the mounts have to be offset just under an inch, so plate itself mounts directly center but the support tube and backside brace are offset. The image is as if looking at the front, so the offset is to the left side of the wheel. If I missed anything or you wanna ask any questions feel free.
