Dang, I didn't put 2 and 2 together. The last picture you posted a couple of days ago had some tape on the rear, huh, 2+2 plus taped frame, Tony's cutting up his bike again!
There are 2 people doing the Sumo now or soon that I know of, I will see if I can find them for ya. They will have what ya need. Or just call Kurt, he may have one sitting around.
