Changing Dashboard Gauge Cluster on a 1966 Barracuda

I’m changing the plastic gauge cluster from a parts dash to the one that came with my car. The previous owner(s) butchered a number of things on this poor car especially the wiring! But that’s another story for another time. I’m trying to bring the original dash back to stock with the original stock gauges.

My gauge cluster is the one on the bottom that I’m using to repopulate from the parts cluster from above.

The gauge bezels were removed from my dashboard cluster and the plastic pins were broken off and I trying to figure out a way to mount my bezels again. The original parts cluster has the plastic pins neatly welded to the bezels.

I’m looking for ideas to affix these to my cluster. Here are some pictures of the back side.

Maybe hot glue through the holes onto the pins? Then easily removable later, if needed.
