It's the oil pressure gauge that uses a copper capillary tube with compression fittings on the engine and the gauge.
The temp gauge was always electric. The temp sender was a nailhead thermistor sender through 1979 1980ish and then various flavors of thermistor senders with differing resistance curves. The less than pleasant reality is that the replacement nailhead senders and probably the others have a different thermistor semiconductor brew than the originals so I'd keep your old ones as long as they work.
IMHO the negatives of the old oil pressure gauge outweigh the positive.
