Couple of updates..

Other than the half shaft, the drive train is complete.

Restoring the driveshaft was simple. I had read somewhere that the u-joints are NLA, but I found them in two seconds at Z Car Depot, so I don’t know what that’s about.

I swapped the flange from my Datsun diff and put it on the Subaru way back, so it went right in.

Hanging the rest of the Spirit Garage exhaust system really felt like reaching a summit. Maybe it’s because now everything I need to do start the car is in the engine bay, which feels more doable conceptually.

The system went in really easily except for a few minor things:

The hanger tab in front of the muffler is about an inch too far forward, so I had to put a bolster on the bolt to take up the slack. I don’t love how it looks so I plan to get two that are half as long. That should clean it up a little.

The pipes hang a little low at the differential crossmember. I had expected them to tuck tight up into the relief on either side of the, but if I lift it any higher it hits the differential. That’s a little bit of a bummer, but it’s similar to what I’ve seen on some others.

Also, the exhaust tips are a little close to the rear valance. I could get different hangers, but I think it will be okay. Still plenty of time to think about that.

For hangers I opted for some universal pieces from Walker Emissions (36273 and 36274) that I just cut to an appropriate length.

So now I just need some stainless clamps and some acorn nuts to protect them from random debris.

Now back to the engine bay.

Some progress:

Reboxed all my parts. It really drove home how much work I still have in front of me.

Wrapped up the remaining AC lines. Pretty pleased with how these turned out. Hopefully they don’t have any leaks!

Refinished and rebuilt my gauges. I matched the green to the inside of my clock rather than the blue from the gauges because the clock was in the best shape. Is it correct? ¯\_(ツ)_/¯

I used warm LEDs, which helped to knock back the intensity of the color. I’m still investigating PWM options to control their brightness.

Added some filter screens and cooling bodies to my carburetors.

Made some hose retainers for the fuel lines with a friend’s CNC machine.

Wrapped up the fuel lines. I may make a rail to clean up some of those cooling body hoses, but it will work for now.

That's good progress! How close are you to being ready for startup?

Thanks!

It depends on whether or not I make the dashboard wiring harness a blocker. If I don’t then I only need to jump some wires in the engine harness, make battery cables, fill the radiator, and bypass the heater. I have everything necessary to do those things, so I could theoretically finish all of that in a week.

I also need to decide if I am going to fill the gas tank now or have the supply come from an external tank.

Oh, and I need to get the transmission into neutral without having a shift stick, clutch cylinder, or clutch pedal in the car.

What he said. In fact, I wouldn't even deal with a tank... I'd just fill up the float bowls with a piece of tubing and a funnel.

Round tops will run the engine for 30-60 seconds before the bowls get sucked empty. I would hope that your carbs would be in the same ballpark.
