You're welcome! Looks like your gauge & resistor check out okay.
There is one other coil inside the gauge movement that you can measure (again with the wires disconnected and meter set to resistance). This time, check between the ground terminal and sender terminal. I think that should be somewhere close to 100Ω if I remember correctly. Pretty rare for there to be a problem with the gauge's internal coils, but worth checking just to be thorough.
If that checks out okay, the positioning / clocking of the needle being off is the only other thing I can think of that would explain the needle going down below zero.
