I opted for ZipTy's replacement bolt on mount, as mine was broken in the crash. I thought I would need bushings, but the new mount did the trick. Looks way strong. The only problem I had was that the mounting holes were a little too far apart. The screws would go in, but I was affraid they would strip, so I elongated the top hole by about 1/16 inch, and the screws went in just fine.
On the rear brake side, the mount was just a little sloppy, so I adjusted with a 5 pound adjustment tool (hammer for those who are not sure). After all the riding I have done, the weld on mount was holding up fine, so the slight adjustment should work for a couple more years.
Now I just can't wait to ride again.
This weekend, I'll install the new ZipTy pipe and build a couple of new rubber mounts...and then just wait. Fortunately, the collar bone healing time gives me a chance to have hand surgery to fix a finger that was damaged a while ago. The doc said a 10 day heal time, so should coincide with the timing of my collar bone. They are even going to let me stay awake and watch the surgery. Too cool. Maybe if I need more hand work I can do it myself next time.
