1) If it seems that the bolts in your plywood floor
are in the same places as the tracks would be, how
about unbolting and lifting up the plywood to see
whats underneath? You may need to remove the threshold
plate at the door edge.

you gotta pull the whole interior to get the floor up. just drill the pilot
holes up from underneath.
