That's coming along quite nicely. I also gave the nearside front wing
a cleaning and another coat, too, since I had the paint out. Really
should finish repairing that cheek panel, so that I can refit this
one, at some point. 
Next on the list, since I was stalled without a drill, was making a
bracket to mount my air manifolds. Step one is finding a suitable
location on the chassis to mount it; right here behind the brake
booster, with these two convenient holes in the chassis, seems a
fantastic place.
Forgot to get a picture of the bracket all welded up, so instead have
a moment of me not thinking ahead far enough. I needed to hold both
halves of this clevis in place while I welded it up, and they needed
to be spaced a certain distance apart, so I wound a nut onto the bolt
to act as a spacer. 
(Thankfully, it did come out easily enough, but there was a moment of
intense concern when I realised what I'd done.)
Rolling on forward to today, I brought my drill home from work, and put the two required holes in the air manifold bracket. At which point, I figured it'd be rude not to start connecting pipes.
The open threaded hole in the upper block is an additional circuit 1 air port for auxiliary uses (like the winch drive clutch, and so forth), and whatnot. Being extremely pedantic about it, technically that's not optimal, because a leak would draw down the air pressure available for the brake servo; but that's no worse than how the truck was originally built, and I can always move it to circuit 3 at a later point if I decide it's worth worrying about. (Circuit 3 is currently earmarked for an air-tool/tyre-inflator supply.)
Anywho, I also went and drilled one of the three big holes in the weld
fixture, which took some time. It does also occur to me that I don't
need those mounting holes to be UNF, and I don't have any free 3/8NF
bolts anyway; so I could just tap them UNC and be done with it. I may
need to move at least one of them over, though, depending on how the
flange sits on the inlet manifold; but I'll have to drill the other
two inlet holes first before I decide that.
Oh, and I did find that missing manifold nut. It was hiding under the back of the offside front wheel.
