Quoted from Tophervette:Good luck finding those lamp sockets. I looked for months, and finally found some used ones in Argentina from a guy Xpablo. I needed 37 of them in white and 10 in black (flashers). Though there is no difference other than color. Rewiring them has been a trip. I am sure there is a tool for that, but I used a thin blade screwdriver to push the wires in.
Someone could make a small $$$ if they could have some made....I need about 40 or so.
