Speedometer cable disconnected for years - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Looks like after the PO made changes, a longer speedometer cable was needed but they just left it. The speedo cable was hanging disconnected behind the instrument cluster and disconnected, hanging off the frame. The speedo port on the transfer case is caked in dirt and oil. Do I just brush out the transfer case speedometer port with a bristled brush and clean it out with paper towels or am I going to have a bigger problem because this type of port should never be allowed to get contaminated?

If it is just a matter of cleaning it off, any ideas on an effective method?
