Water temp and oil pressure gauges.
I have mechanical water temperature and oil pressure gauges in my 63 Valiant.
Here's where the water temp bulb is on mine - in the front of the head above the upper heater hose, between the valve cover and the alternator bracket. Been a long time since I put it in, but I don't recall having to drill/tap any holes.
The oil pressure line hooks to the oil filter adapter in the original idiot light hole. I used to have a T fitting so I could hook up both the gauge and the idiot light, but the T fitting (brass) eventually broke, so I just eliminated it and the idiot light. A steel T fitting probably would probably last forever, but I just haven't bothered.
As you can see, it took a couple extra fittings to hook up, but they are readily available at most any auto parts store.
