Pulled out my antenna cord. Now what?

Hi All: When I went to remove the antenna lead from its receptacle in the side of the AM radio in my 1974 Duster, the coaxial cable pulled out of the male plug that goes into the radio receptacle. The male end was still in the radio, and I had to extract it. It appears that the male end is crimped onto the coax antenna cable in some fashion. Has anyone ever put a new male end on your antenna cord? Does anyone sell these new? If I had a new male plug, I could repair the existing antenna cable instead of trying to find a new antenna cord. Ideas, anyone? Thanks - BOB
