Hole in the Floor

[bubblerboy64]

Just finished installing my air seats. Big improvement in ride quality
and especially considering that my bus does not have air suspension
(steel springs). In the process I found a hole (covered by a obviously
previous owner installed aluminum cover) this hole is right next to the
dog house actually between the dog house and the drivers seat. I would
have to assume it was for a shift lever of some type. Now this bus had
originally the 391 ford industrial motor and I think maybe there was a
second larger ford motor in there before the 3208 was used. I am just
curious about this hole and am wondering if it would have been made for
some other reason then for a shift lever? Would if have been a manual
transmission? Any guesses or speculation welcome. The hole is about
six inches wide and perhaps ten inches long oval in shape.
