39 tail lights

[39delux]

Anyone have a '39?  I need a measurement on the tail lights.  The mounting bosses for my tail lights were cut off and I'm trying to make pedestals to remount them and try and make them look stock.  Anyway, I need the measurements from the front and back of the boss so I know how to make the profile of the mounting pieces.  Think the front is about flush with the body but the back stands out.  Don't want to have them looking like Jack Elam or cross eyed!
