76 Gauge Swap

[vetteengnr]

I am in the process of swapping out some digital gauges that came with the purchase of my corvette.
Electrical issues seem to be abundant with this car, so I am trying
to remove any excess load on the system.
I was able to purchase a set of original gauges from a 69 for a really good price so I jumped on it.
A few of questions:
1) Am I going to be able to connect to the 69 oil pressure gauge? I'm guessing I need a modification to make this work since I have an electrical connector for the 76 gauge and the 69 gauge is looking for a mechanical hose or line of some sort.
2) What does the original 76 electrial system gauge read? Is it a 0-13 scale reading the battery or a -40/+40 scale reading the battery.
3) I have no concerns of #'s matching, how hard is swapping autometer gauges to fit into the existing gauge pod? I know that others have posted swapping the speedo/tach but I've not seen any posts for swapping the center console cluster. It might be more worth my while to sell the 69 gauges since I bought them pretty cheap.

The fuel gauge, water temp, and electrical system gauge all seem to be plug and go, I still have the jury out on the validity of the readings.

Brad,
You are right that the 69 oil guage is mechanical. There was a small plastic tube that ran from the guage to a fitting on the engine near the distributor on the drivers side. Most of the Vette vendors sell this tube as a repair kit. Then you will need the oil fitting for the engine, should be able to get that from most any good auto parts house.

Is the electrical gauge a voltmeter on a 76?:confused
