Got the gauges ready, clock converted, and right dial in the tach, and tested. I had a small paper gasket on the back side of the speedometer dial, around the needle shaft, that came loose, and it dropped down slightly covering part of the odometer, so had to take speedo apart to remove that. Cleaned lenses with Meguiar's PlastX, which worked good.
As I was putting the clock back in the new dash, I noticed the dash holes were a bit tight, and had to pry the opening a little while pushing the gauge from the back. I didn't like the idea of prying on a new dash, even if it was a plastic tool. So, I found a plastic bottle, just the right size to fit through the dash hole, and fit around the gauge bezel rim, after cutting at a matching angle.
And it was slightly tapered, smaller at the ending I poked through the dash hole first, wider at the gauge end. Once the bottle is shoved halfway through the hole, I put the gauge up inside the open end of the bottle and pushed gauge up against the back of the dash, and pulled bottle off. Worked great, plus no messing around the front of the dash gauge opening. I think it was a Clorox wipe bottle, but I'm keeping it! I'll bet the factory had something similar, but better.
Gauges are mounted.
Moved the old clock wires over to the new clock wiring, and have an adjustment switch ready to mount somewhere, not sure where yet.
I also have this leftover part, that white spacer that fell out while removing the gauges. Can't for the life of me figure out where it goes, or even if it's needed. If anyone recognizes it, please let me know. 🤔
Now the fun part, connecting wires back up.
