Bill,
To add to Randall's comments, I purchased a "new" sending unit for my '60 TR3
from one of the big three. When I sent my gauge to Nisonger for a rebuild, they
suggested that I also include the sending unit....they wanted to match the
impedence.
I got a call from Nisonger later that week saying that they were returning the
sending unit me and suggested that I ship it back to the manufacturer. Seems
the "new" sending unit was wound with a different size wire and would be
impossible to calibrate to my original gauge.
I did return the "new" sending unit and Nisonger ended up rebuilding my
original sending unit that I thought was junk. Live and learn.
FWIW
