I did a lot of work on my '50 floor (not out yet). I think the AD burbs are different than the TF burbs. On the ADs they will not drop out. I have body off the frame, all bolts out and it is still held in place. The plywood overlaps metal on the front and back and is under the metal on the sides. I THINK at the factory they dropped the plywood in from the top then spot welded the side strips on. That is my guess on the ADs
Anyway, THREE CHEERS FOR WEEDS ! ! ! I gotta get my _ _ _ _ in gear and take the floor out on mine. Maybe the OMLight AFTER the work is done is the key?
