The original mount was two 1/8" plates riveted together to make 1/4". I ground the rivets off and took the top section off, leaving the two side pieces welded to the frame. I will weld the new plate to these two pieces. I have the Honda engine as low as it can sit and still be level to the original engine which was my goal. I have just enough clearance between the valve cover and the tank rail to bolt on the top engine brace. I originally wanted to mount the engine the same distance from the crankshaft to the kickstart shaft as the original, so that I could use the original kickstart pieces without modification but that wasn't practical. It will still work but just a little more tinkering.
