The motor mount is made from 3/8" steel angle. its welded into a z shape and then drilled to fit the motor mount holes and a u-clamp. I get a pic. The tubes I'm guessing are the handle bars? If so ebay- 10 bucks, along with two others that are progressively narrower in the downward angle (if that makes any sense). If the tubes are the Kenda whites then ebay again - new for 35 bucks.
