Electric Oil Pressure Gauge

I called him and asked him if he could build you one and he said he can.... because he has done it before.

Since you already have a '72 gauge (that doesn't work), just buy an electric gauge (later C3 version) and sending unit, then swap over the dial face from the '72. The scaling is about right ('72 is 0-70 psi; later versions are 0-80 psi). I'm sure that's what the rebuilder would do.

No way in knowing what he would do unless a person calls and asks. I honestly do not think he is that sloppy.

Why not buy a 74 oil pressure gauge... https://willcoxcorvette.com/corvette-oil-gauge-74-74
To do this conversion you'd need to change the gauge housing on the back of the center dash cluster...https://willcoxcorvette.com/corvette...-used-original but the reproduction gauge will fit it perfectly. Then add a sending unit to the engine... Below I'll show you how to wire it. Here is how it installs... but if you get the reproduction gauge you'll not use the resistor, the resistance is built into the gauge on the reproduction gauges.
Then just run your wires... you'll need power, ground and ohms wires...

I did not know that Willcox sells them.
I was more concerned about the patina of your gauge face still being like that of the other gauegs so it would nto stand out or possibly have a different color or font size to it.

I did the Wilcox conversion on my '73 and it worked out fine. Can't tell much difference in the patina from the other gauges . It would make a cleaner installation if you can mount the sender in the plug hole above the oil filter instead of around the distributor area it's kinda tight in that area. I could not get the plug out above the oil filter so had to mount the sender on top .

'68-71 gauges used lettering/numbers that had a slightly greenish tint; "72 and later used white. The font and graphics were similar through 1976 (I believe). Main thing is to buy the gauge and the mating sensor from the same supplier. If you buy a 1975 gauge, also purchase a 1975 sensor so they will work properly together.

The issue is the square hole for the oil pressure gauge.. I've never checked but you may be able to just drill the holes for the oil pressure gauge too.. So I'm looking at the pictures below and don't really see any reason you couldn't just drill the extra holes... I'll have to check this on Monday.

Not so... If you change the gauge housing you'll be fine. The Battery, Clock, Fuel and temperature gauges all mount the same way and on a car with a mechanical oil pressure gauge there was a square hole in the housing...

Thanks!! Looking to swap this out on my 69. Still haven’t decided if I’ll be doing stock gauges or updated ones but I like the idea of no longer have oil run through the interior!

Won't look right on a 69. 68-71 have green numerals, 72-up are white so a 74 gauge will look off. And if you put a 69 face plate on a 74 gauge the reading will be wrong as the mechanical gauge was 0-70 PSI and electric 0-80 PSI.
