I've resolved to remove the added glare shield extension and reattach it with nut plates so I can access the back of the panel. So I drilled as many of the rivets as I could reach, and started to remove the windscreen which is a two man job.

I also bought some hole plugs and filled some unused holes in the turtledeck.

I installed the Peter Anson flap up-stop on the right wing.

I cleaned up some more of the firewall forward wiring.

I drained the fuel tank so I can replace the fuel level probe that I ruined.

And I connected the flaps to their torque tube.
