Gauge cluster removal 68 Barracuda

I ripped my whole car apart and removed the whole dash as a complete assembly. It was easy to work it on the bench after total disassembly. Thought it was all good when I put it back in as a completed assembly after resto. I screwed up and thought all was good. Even after bench testing. Had to remove the cluster afterwards and modernize the gauges in year 2 as I was not happy with the gauges. It was a PITA for sure and do not wish that on anyone. Do it right once and rejoice.
