will this sensor work with a temp gauge that shows numbers vs the factory gauge that just shows a range in green?

No, this sensor is intended to feed the coolant temperature sensor information to the engine computer itself. The ohm range on it will be incorrect virtually anything else that you try to use it for.

It says gm models 1978-2013, it also says cadillac from 1980-1985. cadillac is also gm, so a little confusing. will this fit a 1979 cadillac 425 v8?

It's 5/8' -18 thread. Remove the old sensor and measure, then compare.
