floorpan gaps

I wouldn’t be inclined to drive it like that, make new panels and weld them in.  I only have experience with the Opal and Ruby of a slightly later period. Both of which did not have the drivers side hole . I think that it may have been dropped in later models. I have seen the wooden inspection cap that R mentions in a car of your period and I believe that it had a spring metal clip to keep it in place. Much the same as the one on the transmission tunnel.
