After a dentist appointment for some sensitive teeth, went back out to the hangar with a revised strategy for drilling - being even MORE careful to turn the drill slowly. Result: not much difference. Funny thing: the three or four brand new #30 drill bits still took about 15 minutes per hole. But the old Harbor Freight bits for the #11 match drill instruction took a little over a minute and made a decently round hole. In any event, the job got done.

Then I riveted the F-00055-L-1 & -R-1 GTR 200 Support Brackets and the F-00054-L & -R to the F-01202B-1 Panel Base and I was sure to place the manufactured rivet heads below the subpanel shelf, but then I realized I'd again made the mistake that *I* was the one manufacturing the head (no, Bob, that's the "shop head"), so I drilled them all out and installed them correctly.

I riveted the F-00074-L-1 & -R-1 Garmin Xpndr Firewall Brackets to the F-01201A-1 Firewall Top, placing the manufactured rivet heads on the forward side of the F-01201A-1. So I got it right that time.

Access is pretty limited in the front so I had to pull some wires back around the GPS antenna shelf, which caused the two split rubber grommets to fall out. Putting those back was a blast.

Next time I'm out at the hangar, I'll mix up some ProSeal to cover the rivet heads.

I wonder if it's OK to reinstall the fuse box.
