I agree with The Rocknrod on the oil gauge ... you'll need to remove the existing oil light switch and replace it with a tube for the mechanical oil gauge.

However, on the temp gauge, it appears as though your existing cluster already has a gauge (instead of hot & cold lights). So as long as the existing temp sending unit is functional, I don't think you'll need to change that.

The 1960 through 1962 factory tachometers used an external transmitter box. And the transmitter box is what's different for 6 vs. 8 cylinder applications. I know the 8cyl applications typically used a Sun EB-9A transmitter, but I'm not sure about 6cyl.

The tach should have 2 terminals on the back marked + and -. Those connect directly to the corresponding + and - terminals on the transmitter box. The "dist" terminal on the transmitter box connects to the negative coil terminal and the "grd" terminal on the box goes to ground. They originally used a 1.35V mercury cell (located inside the transmitter box) for power but those are no longer available. I've heard that a regular 1.5V alkaline AA cell can be used as a substitute but might make the tach read a little higer. And I believe many tachometer repair shops can replace the old guts in the transmitter box to eliminate the need for a battery.

To make the BATT gauge functional, I think you will need to add a couple of wires to the engine & front light / generator harnesses. Unfortunately, the wiring diagrams I have for 60 & 61 don't show the connector pin-outs like they do for the later years so I can't say for sure, but it looks like the cab / dash harness may already have the necessary wires for the BATT gauge present but simply left unused.
