1971 Dash / Gauge Cluster Removal

More common errors installing new bezels... Over tighten the screws that attach the pot metal instrument housing and you'll see dimples in the face side of the bezel. at those screw locations.
Use improper tools tightening switch bezel nuts and really screw it up.

Other assembly errors... leave any of the 4 gaskets at indicator lamps out and you'll have light misdirected.
Get locations of Oil and TEMP gauges wrong and you'll take it all apart again. That mistake is very easy to make. I've seen all these errors 3 or more times.
I've seen brand new bezels broken by the right seat back too.
There are more. I wont type them all here.
