New 75amp alternator..blew fusible link.

Well I bought a new link at the auto parts store and had to splice it into my wires. It works and runs again but it aint pretty. Have original old brittle wire still going into my buldkhead connection. I cant figure out how I could replace just that terminal without having to replace the whole connector. Any ideas? It's just e-taped and spliced into a a new link now...but it runs!
