73-77 Oil Pressure Gauge: Picture needed

[Fan2zee]

Could someone post a picture of the backside of a OEM style Mechanincal Oil Pressure Gauge from a 73-77, C10.

What has happen, when I purchased my 87' C10, it has an aftermarket Mechanical Oil Pressure Gauge. A great person from this site, had an extra OEM style electrical O.P.G. they sent me. Once I was installing this Electrical gauge, I reallized someone drilled through my oem Printed Circuit board to install the aftermarket mechanical O.P.G. The OEM electrical gauge will not work without puchasing a new Printed Circuit.

So I'm thinking of replacing the Mechanical AfterMarket O.P.G. with a 73-77 OEM style replica gauge, and wanted to see if it has the same plumming as the aftermarket one that's already installed.... so I may keep my dash looking OEM.


Thanks..
