Hi Tab
I had the same thing happen on my '62 too. :o
I found a replacement guage cluster on Ebay, these are always on there. 1960-63 Chevy guage clusters are the same. They did make a few different ones. The first one has the dummy lights, the second one had needle temp + fuel gauges, the third one had 4 needle guages with or without the vacumm guage + factory tach.
I hope this helps.
