Hey all, I have a unique question that I need answered..My dad, who owns a '56 is in the process of milling some rear brake/taillight brackets. He is making his own that hide the wires and feed them into the back of the taillight housing..Neither he or I have a taillight housing so I was hoping you all could help by giving me/us the diameter of the hole at the back of the housing that the wires feed into..

(Oh ya, just in case there is any confusion, I am talking about the stock "shield" taillights..)

Thanks for the help!
