Good ideas F Bill.
Here's what I have: I think this is the oil pressure sending unit. Not sure if I can or how to use this piece. I've seen replacement units, but not sure how to connect the sending unit to the gauge.

This is the temp sending unit (I think). I tried to use a replacement unit (for the Fhead) but the temperature sending unit did not fit in the threaded hole. It was too big. Is this the right spot?

Lastly, here are the gauges in the dash. The chunks in the oil gauge I think are what's left of a gasket maybe? The Temp unit is in a box somewhere....
You can see how I couldn't pass up buying this jeep...it's got less than 3500 miles on it!!
