I'm working on my 56 pickup, finally.  One of the projects is installing pedals and master cylinders from a 59 with hanging pedals.  The reinforcement plate from the 59-60 models will interfere with the big wiring hole in the firewall.  So I need to weld it up and make a new one.  finally the question:  Does anyone have a 59 or 60 and could take a pick of the driver's side firewall under the hood?  I would like to locate the new hole in the factory location but I don't know where it was
