If anyone identifies a source for the nichrome or someone who is rewinding boards, that would be great.
The heart of the problem of the replacements is the board and the float arm length.

@Cuda Al shows his repair in detail -
Fuel Sender Rebuild
as does this How to article (except he gives up on fixing a board with busted wire - as I did at one time)
OEM Fuel Sender Repair 1967 Dart
Thanks. Good info.
Part numbers I looked up in the FSMs were:
1967 p/n 2257 493
1973 p/n 3621 615
Several changes in fuel formulation in th 70s. One of them may have resulted in greater reaction with brass.
