TOPIC: Mercury Stern Light

Does anybody know the years Mercury offered the Stern Light for the Mark engines? I have one on my '58 Mark 55 and want to add the other to my '59 Mark 58A. I want to make sure all is kosher on this baby, I am putting enough money and effort into having a show-room quality restoration, I don't want to screw it up by adding an option that wasn't offered that year.

Thanks, Thom
