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
