i know you asked @Hank6760 , hope you don't mind if i weigh in on it. when i did mine which cut just a titch lower, i burned a 3/4" pipe on top of the 2x4 tube then stitched the body to that. the back side was cut to the bottom of the tube then stitched to the corner of that. i hope hank doesn't have take his front fenders off, it'll be grinder time. mine i'm planning on using some sort of self-tapping fastener for that bottom edge. the 3/4" tube fit nicely into the radius which hank cut off. i posted up pics in my build thread " the dragonship" if you're curiousLove it! Question about the sliders, I'm planning to do the same thing. Did you initially stitch-weld it, then weld the whole thing later?
