We attached the throttle and prop cables to the tunnel cover and the throttle quadrant levers:

Cable ends secured to the quadrant levers
Turns out that there was still some interference with the center console in certain lever positions, so we sanded the center console lightly in that area:
Area of interference between center console and control cable
We then secured the cables to the firewall with the TTP-S fittings. I thought I'd have to secure them in an intermediate place (e.g. using F-1083), but they're still enough and held firmly enough in place by the fittings that there's no chance of them hitting the rudder pedal arms - we held them together with friction tape just to be extra sure:

Control cables coming out of the firewall on the forward side
I secured the coil pack mount to the engine mount structure using a trimmed aluminum angle and Adel clamps:

On that position, I also used the top hole to secure many of the engine wires with another Adel clamp:

Some people have asked me for a drawing to reproduce that part - here's the closest thing to that:

I also installed the oil pressure hose from the engine to the sensor:

This section also has you run the heat valve control cables to the panel (I'd expect that to be part of section 50, but oh well), so we attached those - one of the center side panel, the other to the center console insert, routed them through the firewall, and attached the center console in that position:
Heat valve cable secured opposite to electrical wires over the tunnel
Running the heat valve cable over the tunnel
Heat valve cables (on the copilot side and passenger console) installed in place
The main things left for this section are securing the heat control cables to the firewall and valves, and connecting the MAP sensors.
We fixed the rivet on the panel angle, which turned out to be due to the firewall angle hole being oversized - so we used a CR3243-4-4 oversize cherry rivet to attach it:

We're using Skybolts instead of hinges for attaching the cowling to the firewall, so I started that by countersinking all the Skybolt flanges:
Skybolt cowl flanges countersunk for riveting
We also installed the glareshield cover, starting with cutting heatsink and cable holes through it:
Trimming the glareshield leather cover
Punching holes in the glareshield cover for attaching fan covers

Glareshield cover installed in place
It was impossible to get the panel frame into place (get the holes to line up) with the thick leather+foam, so we removed the foam from most of the bottom part, which allowed them to fit together:
Removing some of the foam from the bottom side of the glareshield cover
I also opened a small slot on the flange of the panel in order to run the glareshield LED wires (the connectors will be hidden behind the panel frame):

We installed the panel frame in place, and tucked the glareshield cover in:

I then secured the parking brake cable to the bottom side insert, and we installed it in place:

If I knew the whole geometry of this cable run back when I installed the Beringer system and hoses, I'd definitely have placed the parking brake valve in a different location (maybe above the center tunnel, or even on the firewall).
I also had to trim the top edge of the side panel to give avoid the bottom connector from the VP-X (seen above).
Last but not least, we attached the arm rest cover to the center console:
Center console with arm rest cover installed

The main thing left in this section is the cowling attachment, since between this and other sections most of the panel's structure is in place.
Time lapse:
Total upper forward fuselage installation rivets: 153
Total upper forward fuselage installation time: 42.7h
Once the engine mount was in place, we could finally attach the floor covers:

I also opened a slot on the tunnel cover for wires - I was originally planning to run the wires through it with the cover in place, but after actually doing the tunnel wiring I realized what a royal pain that'd be:

I attached the seat floors for good:

We also started trimming the forward interior panels, but that'll take some more work to finish.
To finish up the aileron actuation section, I installed the main pushrods and the left bellcrank (the right bellcrank had been installed along with the autopilot servo):
Main aileron pushrod attached to bellcrank
Main aileron pushrod attached to wing root torque tube
I also took the opportunity to complete the last step from section OP-38, attaching the springs to the roll trim servo (and then shortening the wires enough that they don't hit the nearby screws:
Trim servo springs attached to aileron pushrod
Trim servo wiring inside the wing
When I mounted the actual aileron in place, I realized that, as it got actuated, it'd rub against the bracket rivets next to it, on both wings - so I replaced those with flush rivets:
Interference between a rivet head and the aileron
Interfering rivets removed and countersunk for flush-head rivets
Flush rivets installed on aileron brackets
I then attached the aileron-to-bellcrank pushrods:
Aileron-to-bellcrank pushrod installed
With that, the only remaining step in section 23 is actually attaching the pushrod to the aileron.
I followed the ZipTips manual I wrote for the left wingtip, using the hinge attachment method for the bottom side in order to properly ground the Archer antenna to the wing:
Left wingtip marked from trimming for hinge attachment
Left wingtip attached to top skin
Match-drilling hinge to bottom side of wingtip

I modified the Archer NAV antenna for better ILS reception, with the center strip that Martin Renschler designed (and very kindly distributed at Oshkosh):

The antenna and the hinge were then secured to the wingtip's bottom surface:
Archer antenna and hinge clecoed in place
Archer antenna and hinge riveted in place
I drilled and countersunk the inspection panel's holes (for tinnerman washers), and installed nutplates to secure it:
Inspection panel drilled for attachment
Nutplates installed to hold inspection panel
I match-drilled the forward holes to the light module:
Light module match-drilled in place
At this point, it became evident that the hinge had a problem - it was slightly misaligned, making it nearly impossible to insert the pin :( That'll have to be fixed soon.
