I am in the process of doing some dash and instrument restoration on a 69 vert. This will include changing the fuel guage to a factory tach and installing the autometer guage pod. Also I wouldn't mind getting everything out for cleaning and checking connections. I have the dash pad off and loosened the main cluster. I thought this was just a cover but everything is attached ie. heating controls, speedo, lights, etc. It does not want to pull out due to all connections. Am I missing something? Do I have to disconnect everything from the back first. The heating controls look miserable. Any tips?
