Here are pictures of my bracket. I have the dimensions that I can try to scan. It works well and is very easy. The only change I need to add is a radius to the lower corner where the dial indicator mounts. That would allow it to swivel more. Once you screw it down, it is rock solid. You have to get the indicator with the mounting stub on the back side.
To answer Glenn, I am not sure if they make a 2 degree offset. I think it might be 2-1/2?
If you want to add the bracket to the tech manual, I can try. Not great at that sort of thing!
