Bulkhead connector block

I think the bulkhead block where all my electrical connections coming through the firewall is going bad. Just recently started driving the car a little and now when I hit the brake pedal one of the front parking lights comes on. Instrument cluster lights don't come on when the light switch is pulled, but when I pull the emergency handle they come on and the further I pull it the brighter they get. Gas gauge is new and and worked fine but now when I hit the brake pedal it will go to full, let off and it goes to empty. Does anone reproduce these bulkhead connectors for a 67 Dart. If not is there a better fix than just replacing it with another factory one?
