Staghound Hydramatic Transmission Question

[Malcolm Towrie]

I checked out the Stewart Warner site but it seems the temp sender info doesnt give any degree-to-ohms calibration info (at least I couldn't find it), so they can't be matched to an original gauge, just a new SW gauge. Which is still a good option.
Also, none of the pressure senders, which do give psi-ohm calibrations, match the 0-30 ohm/0-60 psi calibration I found the original gauges have.

However, I did find this good information on all the NAPA Echlin senders and switches which allowed me to find a 5 psi low oil pressure, NC, 1/8"'NPT warning switch and a 250F high temp switch.

In hindsight, maybe I could have found senders for the original gauges with this list.
