72 bucket seat floor supports

If you are in a bad wreck you don't want that bucket seat and you flying thru the windshield and beyond because those nuts on those bolts holding the seats down went thru that thin 18 ga. floor sheet. I make mine and weld them down. But I have been hit head on by an 85 mph drunk in a 65 Lincoln. Dunno he might have been doing 90. He was fast.....he ain't fast no more and hasn't been fast since 1975 was it. Drunk SOB.
