Another option for tailpipe brackets would be to bolt a replacement clamp onto the appropriate length strap. It wouldn't be perfect but it would pretty close and would save a lot of fabrication work. This mob appears to have the correct clamp (bottom left of top pic):

Keith, your clamp is pretty close but the "correct" one is asymmetrical.
