Suggestion for finding correct instrument voltage limiter for 67 Dart

Some general ramblings:

1...For SURE get a modern solid state replacement, and not a mechanical one

2...It may by another problem. It's known that the harness connector pins get loose/damaged on the PC board

3...It's known that the contact "socket" fingers where the IVR fits lose contact with the board traces and you have to solder them across

4....The "fake nuts" on the gauge studs allow looseness/ corrosion. Loosen/ tighten the nuts a few times to "scrub" the connection, /and/or replace with "real" nuts.

5....Please READ THIS THREAD It covers repairing these problems
