I am investigating replacing a couple of meters with digital meters. I have the option of receiving new sensors with various threads. Is the stock thread for the Oil Pressure Switch and the Water Temperature Sensor 1/8" Pipe Thread or 1/4" Pipe Thread or some metric pipe thread? I have not been able to find anything definitive in the FSM and probably would not recognize the difference if I had the sensors side by side.
If you are looking at aftermarket gauges and need to know the correct thread for the sensor, I just got back from Autozone and screwed adapters onto the Oil Pressure Switch and the Coolant Temperature Sender (not the one that goes to the computer, the one that goes to the gauges).
Lou, I think you might find mechanical gauges with different threads. If you're considering doing this on a 3800 intake, I would procure my gauge first and determine the thread size before drilling and tapping. The 3/8 is the size of the stock Fiero sending unit for the in-dash gauge.

Edit: For some reason, I didn't see Larry's last comment. Double post on my part, I guess.
