Working on my 55 (yes, been gone from the forum for a while). I'm a the point where I'm taking care of some of the holes in the interior, then ordering heat shield then carpet. I know one of these two holes was for the floor starter button, but not sure about the other. I plan on welding a piece of metal over the holes to keep out the fumes; and maybe in a few years put the foot starter back in (there is a lot more I need to do to the truck and that is not on the priority list).
