I also wanna join the club of the borken targets. I got a nice Indy 500, but of course the targets were broken. I created an easy fix for every one with a 3D printer. It's a "slip on" solution and you don't have to take off the target which is a pain in the ***.
you can dowload the *.stl file for the 3D printer here: http://uploaded.net/file/l63qtaki
Just cut down the rest of the broken target.

put a bit of glue on the marked positions

So at the end it looks like this:
