Retrofit AMP meter

my (1972) amp meter was doping about 3 volts under load causing a lot of issues. I dont know how different they were through the years but the studs/posts on the 72 meters were not attached and were not held in this is easily fixable with some silver solder.

67's was held in the same type of stud as an electrode from an oil burner off a boiler. I'm not sure how the 72's are. But I know that they're a bit easier to retro fit. I did hear something about doing that though, but I still have all the original wiring, I don't want to take that chance and the car burn down...
