Next, I clecoed the F-810A aft bulkhead in place and attached the ELT antenna cable to the bulkhead fitting. Since my homemade F-810A has a smaller lightening hole than the stock bulkhead, I'll probably have to use blind rivets in some areas, and I can already tell that tightening the horizontal stab bolts is going to be a challenge, since I can't reach my hand through the hole.

I also primed the two spacers that will reside under the front spar of the horizontal stabilizer.
