Since I'm converting from auto to manual I have a tranny temp sensor I can move and re-use as an oil temp sensor. Any idea where there's an access location to an oil passage without headache? Early model SBF, '68 302. Thanks!

If you really think you need an oil temp gauge, you could probably install a tee fitting in the same place your oil pressure sender goes.

If you do install it, I'd be curious to know the difference you see between your coolant temp and your oil temp.

Not a Vintage Mustang but likely relevant information:

On my ‘02 Jaguar XKR I have both oil temperature and coolant temperature readings coming off the OBD-II data stream. After the engine is fully warmed up, the oil temperature is nearly always 14 to 16 degrees F higher than the coolant temperature. A typical reading is captured on the Autool X-60 that I installed in the corner of the dash. The car has a 4.0 liter V-8, supercharged. The other number displayed is the ignition advance.

The easiest thing to do would be to weld a bung in the oil pan.
^^^ This. The only way you'll get an accurate reading is to have the bulb of the sensor immersed in oil. A "dead ended tee" isn't going to give you a good read.
