Tested out the battery pack directly on the starter of another car at home and that seems to work. Hopefully can get it home. Roll start might be easier but the road is flat and fairly busy.
I'm wondering if the one wire type is for electronic ignitions. An EI doubles the number of amps to the two wire tach, as it runs in series with the coil. And installing an EI is known to fry the factory tach.
I believe we what have here is a B210 round tach on the left, and a B211 on one the right. Note the different wiring. The B211 one looks like a one wire tach. It has a single black/green wire. The B210 one has a pair of black/white wires.

I wonder if you use could use the ordinary harness? The main cluster and tach should be fine.
Then make a little connector from the clock plug to share with the Amp/Volt meter, and the oil gauge. Then just add a wire from the oil pressure sender to the oil gauge. The Amp meter has extra white and white/red wires. The volt meter just has one plug like the clock.
