Hi, I'm working on sons 72 cutlass,taillight not working.Removed bumper and taillight housing .Broke plastic pig tail that goes into top taillight housing.Taillight socket spins but can not remove.I would like to replace wiring pig tails and sockets if needed.How do you remove wiring pigtails and are replacements available .Do the sockets need to be removed if so how do you remove.Thank you Andy
