Electrical Connector (Bullet Type) for Instrument Cluster

I am going over the entire underdash harness for my 69 Dart. I noticed that the previous owner was hiding a problem that may have been part of the culprit to the problems in my instrument cluster. One of the female bullet connectors in the five-pin connector on the left side of the cluster (temp and fuel gauge side) was essentially broken off inside the connector body. I pulled the wire and connector out to repair it. Unfortunately, I have been unable to find a female bullet connector the correct size to fit back in the plug. Is there any chance that someone here on FABO has something like the connector that is pictured or knows somewhere to purchase one? I have checked all local auto parts stores and Radio Shack and they simply do not sell this particular size or style. The connector is 5/8" long and the female opening is about 1/8" or 3.5-4.0mm. Any assistance would be greatly appreciated. This is the last piece I need to complete my harness work.
