Rallye dash gauge upgrade

When I bought my car 6 years ago I did not trust 40 year old gauges , sent them to be rebuilt . Email the people in the post above and ask them what they do to the gauges in the rebuild , they did something when rebuilding the fuel gauge and built up the ammeter to prevent a melt down . I was paranoid about a melt down as it's happened to me on my old 1977 Dodge ramcharger , a few $$ to prevent that is worth it in my books .
