source for new tailight socket???? 65 dart

Went through this myself and tried many different new ones but not the ones mentioned previously and could not get a desirable fit. (Napa, Pep Boys, O'Reilly, Autozone and Walmarts DID NOT FIT GOOD) I ended up using the old sockets with new wiring added. Works like a charm and fits better then any new ones I tried.
