While you are at it you should solder the rivets on the back of the panel that tie circuits together. Jonny hinted at it.

What happens is the rivet will start to corrode. May not even be noticeable, but will create some resistance and then heat. I had a block burn up when that happened to me. Just take a good solder gun and run a bead of solder over the rivet.

You will be surprised how much resistance there is on the fuse block where the fuses connect. With the car running take a digital volt meter and touch it to both sides of a fuse. I was getting .5 volts on some fuses. Not good. Same technique can be used on light sockets or ground connections. You would be surprised at how much resistance may be hiding in one of these old cars.
