This rear, middle cab floor panel was included, loose, with my M2A1. The three screw holes along the rear edge are about a half inch too far to the rear to fit the holes in the flange on the rear bulkhead. The other panels fit the bulkhead fine.

Also, there are four holes in it that have ¼-20 square captured nuts. I assume they are to accommodate a middle seat configuration for a different model half track?

I could weld the rear holes shut and drill & spot-face new holes in the correct location, but I don’t want to modify a panel that is the “right” one for a different model half track. Can someone identify this one? If it is for something else, I’d be tickled to trade it out for one for an M2A1. Thanks.
