the best way to repair them is to get some heat shrink with the goo inside, unhook the cable and slide the heat shrink over and heat till it forms up, should take care of it.
Thanks for the ideas I don't know if the heat shrink would work in this case as the metal in the casing is sticking out at all angles and would just punch holes in the heat shrink. I may have located one from a 64 and I'll just change it out.
