B/U light socket replacement

That is a very true statement. I agree 100% especially with a light assembly that you cannot find a good replacement for with a stock socket. however the way most of these vehicles are now restored and pampered if your stock sockets are fairly decent and restored, they will probably outlast your lifespan with a glob of dielectric grease in the bulb socket.
I had a messed up Tail/turn on my Swinger. Good thing a buddy a hour north had a parts car.
