If you know which resistance value of your sender than you can cross reference it to an aftermarket unit. That's what I did with my 47 Packard. But since my unit was a basket case, I hooked up some resistors and calculated that I could use the 0-30 Ohms sender which works with most pre- 1965 GM cars.

Ohms/Resistance
(Empty/Full) Popular Models
0-90 Ohms most GM cars, 1965-up
73-10 Ohms pre-1989 Fords & most Chryslers
240-33.5 Ohms Industry standard, works on many popular cars
0-30 Ohms most pre-1965 GM cars
16-158 Ohms most '89-up Fords


All gauge (temp, oil, gas) senders on the 51-56 Packards are King-Seeley resistance type. Those senders use the 73 empty 10 full range as in Fords and Chryslers. 6 or 12v is not an issue as the gauges are regulated to 5v.

1950 and before gets a little confusing and varies by the type gauge. 0-30 may be S-W's range in use then since many models appear to have had S-W gauges. My 47 does and I believe some prewars did as well. It gets a bit more interesting with the cars that have the bimetal type senders. I believe 22-23rd series fall in that group.
