Can '64 Dart Temp Gauge Be Adjusted?

Didn't see how to take the screen off on my '64, so I went in the back of the can. I can bend the tabs back down with my smallest needle nose plyers and my BFH:D

So to recap, I insulate the back of the fuel gauge can from the panel housing, replace the cheesy tin speedy nuts with real nuts for a better connection, and pull the 12vt lead out of the pin connector to wire the new regulator.
Pardon the redundancy. Sleep deprived and this decafe' coffee isn't cutting it!:eek:

The screen is either crimped onto the rim of the can or held with 2 small brads in rectangular ears on the edge of the can. Either type is pretty easy to open (if/when necessary).
You could just use a wire brush in a dremel to clean away the rust. Hardware will be 10-32 hex nuts and internal toothed washers just like those on the amp gauge. Home Depot has them in small orange plastic packages hanging on a wall. Yellow packages are stainless and cost more. Use them on top of the speedy nut where you'll place a ring terminal of the 5 volt wire from your regulator, if you dont use them everywhere.
I've ran into a few of these studs that a hex nut would not go on. 3 or 4 in the course of 8 years and few hundred gauges. Evidently there was no need for tight tolerance or quality control since they weren't going to get a real nut anyway. Also ran across a few that were so rusted I had to cut the speedy nut off of them. Running a die over the threads to clean them up is tedious labor. The board is very easily broken.
