Add me to the broken Tap in the rollbar club. Wish I had used a higher quality tap and been more careful. 4 inch crack running back that I stop drilled. I am going to trying gluing it with Weldon #3 I guess. I wouldn't recommend tapping through the canopy, its just too risky and multiple people have messed it up. I would spend the time being careful keeping the tap straight or building a jig for it after #36 holes are drilled. I am a bit devastated and now need to decide what to do on my special order rear canopy. If I get a replacement canopy will I be able to line up the holes well enough without ruining the threads to get a good fitment? Who knows.
