Given time, I have answered my own question. After ordering several sets of handlebars, I have chosen two. One set is from ebay and is sold by Legends Motorcycles, Inc. in Colorado. They have sufficient rise and a short enough cross bar so they can be shortened and still allow ample room for the controls. The other set comes from Strictly Hodaka and has more rise and a longer cross bar. I think I can shorten them enough and still have room for the controls. I plan to try both and see which one I prefer.
