Since the Packard method of testing all the gauges was to use a fuel sender I would expect the oil and temp senders would have a similar output to the standard 10-73 ohm range of the fuel sender. The OP6091 oil sender from Napa has been proven to work by several and the TS4 temp sensor seems to have a similar output in the working area of 125-212 degrees

One thing on the Ford fuel sender to check is the arm length. Apparently Ford still had two sizes of tanks in the 50s just like Packard had before 51. Some of the Ford senders have shorter arms for their small and I assume thinner tanks and will read incorrectly in our tanks.
