Some of today's progress:
Assembled doors installed/gapped. Driver side adjusted fine, but passenger side was out a mile. Turns out the tub and cowl weren't as square as I remembered so had to loosen some fasteners and shim one side out. Worked fine and we've got nice even gaps now.
Cluster wiring/lighting finalized and bolted up for the LAST TIME. The centre dash piece will have to come out for a pewter paint job when I get some of that colour mixed, but otherwise it works great. I ordered the danhard heater with mechanical controls so I installed them in the factory panel which makes me happy. I still need to make a bushing to adapt the factory metric nobs to american thread stuff, but that can come at a later date.
Danhard heater installed. This is a generic thing, not a 40 series part, so it is not a bolt in installation. Its quite a deep unit so naturally does not come close to fitting in the stock location. It does fit nicely under the glovebox, however, and it doesn't even come close to interfering with the passenger's foot space. The downside is that the ducting for the defrost has to run through the glovebox, but it doesn't bother me at all. The heater runs off the 12v converter that is also stashed in the glove box.
The some of the remaining wiring you see hanging down are various ignition and accessory wires that I have yet to use, and also wiring for the ARB compressor hidden in the storage tray in the tub.
Here's a couple pics of my mess.
