Canopy fits, so this has been riveted in there. Seems fine.
Also, all these holes have been tapped. Woop de do.
Months ago, when I was putting together the rollbar and attaching it to the plane, I got an email from another RV-7 builder that warned me not to attach the rollbar brace - that was already attached to the rollbar - to the back bulkhead - until after the back window was attached. (I don't even remember who this was, now, so if it was you - thanks, whoever you are.) He had apparently riveted his rollbar brace onto the back bulkhead, and then found that his canopy was a bit more thick than the plans apparently thought it would be, so it would not fit in there. He had to drill out all the rivets, and move it a bit farther down the bulkhead, apparently, and then everything was fine.
After hearing a story like this, it made sense to wait until we could make sure our canopy would fit before actually riveting it, so we did. When we got the canopy in - to my surprise - it fit just fine, so tonight we riveted the rollbar brace to the back bulkhead . . . several months after we could have done it, as it turns out.
Still, I think it's a good idea to pass this advice along: your canopy may be a bit thick back there, and it doesn't hurt anything to wait until after you fit the canopy to rivet the rollbar brace to the bulkhead.

I've heard at least one RV builder talk about how you can get your tap broken off when you're tapping these holes. I guess it's possible, since someone has apparently done it, but I really don't see how . . . this seemed pretty straightforward to me.
Great. After typing something like that, I bet I'll break two or three taps in the next week.
