Installing mech. oil temp and mech. oil pressure gauge?

I'd like to install a mech. oil pressure and oil temp gauges. Could I run a t setup ? Or bad idea??

Or would drilling the oil pan for the fitting be a better idea? (oil temp)

It's on a /6 bracket engine if that makes any difference.

i don't think a tee would be the best idea, having some oil movement around the bulb would give more accurate results.

Drill and tap the oil drain plug for the temp sensor.
