Update on more Found Parts...
I'm still not entirely convinced the Molex Connectors we have access to today are the same model/version as those used in the filming of ESB. If you look at your molex's you'll see a line of 4 small circular markings in between the 6 hole pattern on the front face. Looking at any clear shot of the molex's in the film, you'll see that the two center ones of these appear to be actual holes (likely for locating/grounding pins of some kind) rather than filled in casting markings like on the new ones. I ended up drilling these two holes out on all the molex's on my build until I can find some more original ones

Do we have any images of an actual molex manufactured with those small holes?
