I just thought of something that might help with the bracket to keep from anyone else cracking their undertail.... maybe putting some kind of piece of rubber ( or what ever you can get that might be soft and plyable) between the bracket and undertail to help cusion the tension between them when you tighten it down... it should help instead of having two hard surfaces being smashed together you would have a "gasket" to help distribute the pressure between the two.... just an idea and i will be doing something like this myself after seeing these pictures...
