Default gauge space

I would like to add a vacuum and A/F gauge in my 78 pace car. Any good ideas on how I could add without modifying my original panel. i.e. a rt vertical windshield post etc.

It's a pretty small passenger compartment in the C3's. I've mounted extra gauges in two different spots on my 68. First I mounted a voltmeter (68's have ammeters not voltmeters) to the left of the gauge cluster at the bottom right side of the drivers dash pad. Recently, I removed that gauge and added a voltmeter and fuel pressure gauge directly underneath the right (passenger) side dash pad. They're clearly visible from the driver's position. Let me know if you want me to snap a picture of the gauges for you. I personally think it looks OK (obviously not original looking at all).

I seriously hope your fuel pressure gauge is electronic. Mechanical fuel pressure gauges should NEVER EVER be used isnide the car.

Yes, electronic fuel pressure gauge by Longacre. Fuel pressure sensor near the carb wired to the gauge inside the car.

I replaced my clock with a/f gauge. The car is also non-A/C so I put a transmission temp gauge in the vent hole.

I installed an electric fuel pressure gauge on my vertical "A" post. It uses a sensor on the fuel line at the carburetor. Here's a photo...

This will only work if you have an L88 hood, but it may give you some food for thought...

If you are willing to give up your radio you can do something like this



I've put an iPod classic in the ash tray. Apple doesn't sell these anymore but I've seen a number of creative replacements on this forum.

Also many of the aftermarket gauges have multiple functions. You should look into that. The AEM gauges I installed have replaceable faces. I designed my own face to match my original GM style but didn't follow through. It can be done though.

Take out the clock! I know it's a slight panel modification but it would look quite stock to the untrained eye

You can never have too many gauges!

Thats where I am looking hard at. I think I can get 2 or 3 on the right windshield post by modifying a Auto Meter aftermarket post.

Thanks for your response

Very nice, I am looking at the ash tray area as well
