My oil pressure gauge is where the original sending unit was threaded in to the block. You will have to get metric fittings for that.

My temperature gauge is located where my drain plug was. It is not completly accurate but it does work ( I just add about 20 degrees to get a true reading plus I have the factory temp gauge that works). There have been good arguments on the location of the temp sending unit. Obviously the best place is just after the thermostat but with the sami configuration it is limited unless you get a pipe/tube that has the connection welded in it and cut a section of the top radiator hose and replace it with the pipe or tubing. This way you can keep your stock gauge and have the aftermarket gauge as well.

The sending unit directly under the upper radiator hose is the factory sender for your dash. The larger one to the left of it is the thermal switch for the stock carb/ECU combination. If you are running a Weber, you aren't using that thermal switch and can remove it, thread in a bushing and put in an aftermarket sending unit there.

If you do that, here is what it looks like (look at bottom right):


Before I redid them, this is how my gauges looked in the dash, pulled in this view so I could get to the wiring:


All of my gauges are Sunpro cheapies, I didn't really want to bother with anything worth stealing. I went with a larger tach:


Here is how they look mocked up:


Now, on the driver side of the block, here is a pic of the oil pressure sending unit:

I also chose to use terminal strips mounted to the firewall on the passenger side under the dash to wire up the gauge lighting and power:


The crimped connections have since been soldered, but the point here is the upper strip is fused, key-on 12v power and the bottom strip is split 1/2 positive (red) and 1/2 ground (green) for gauge lighting. You have to tap the positive and ground for this into your dimmer switch wiring (both positive and ground) in order for you to dim your gauges off the factory knob.

Any idea on what thread size the larger temp fitting is on the intake???

this is what I have considered doing with mine


And here is a link to the entire wright up

I don't have oil pressure but I've been running a scan gauge 2 on mine through the obd2 port access. It gives me access to everything the ecu gets I mainly use it for water temp, volts, intake air, and rpms. I laminated a list of trouble codes and I can check them out in the field as well. Serves two purposes. Just giving you options

The PO had put four large tweeters out of a box speaker for home use in the openings for the air vents. I removed the two middle ones, the other two actually work really well, so I left them, I decided in the holes left, I would just put gauges in. Volt meter and oil pressure.

So far I only have the Voltmeter.
Its a 2inch gauge so it didnt fit well, I took some hardboard(kinda like the walls on cheap speaker boxes) Put two hole saw blades on the bit, one the size of the gauge, one the size of the opening. I then took foam and did the same to make it snug in the hole. Worked well. I put bed liner on in to make it look better.
