I finally get my 65 Belvedere (creep) wagon back. A bunch of little things to do but I'm driving it finally. So the fuel gauge stopped working. I checked everything at the tank and then went under the dash. As I undid the plug at the cluster, one of the pins broke. Ugh!!! It must have been corroded. Anyway, can I just get a new gauge or do I have to replace the whole cluster?
