A Stovebolter, Sublime, did a 46 on a full size frame when I first joined the Bolt. He added a 4' strip to the fenders to widen the stance. It had a flatbed on the back. I can remember being awestruck at his fabrication ability. I looked him up here and the last post was in 2007. He had an excellent photo album but I couldn't get to. Probably like Webshots.....where I lost all my early pictures. Anyway pretty much anything you would like to do can be done but the beauty is in the eye of the beholder.
