Thanks for the reply, and the info. The nighthawk that I have came off e-bay. It came less rear wheel, seat, and motor. I just did a bird wren, when I seen this one, and couldn't resist bidding on it. If I can't locate a original rear wheel, it looks like I will have to update to something else in a 10" rim. If you have any ideas what would look good let me know, Thanks again, Gary
