So the guy I got my 70 from welded 1/4 plate in for new floors.
Always figured that was fine, and of course they would never rot out again.
Then I recently decided to do a 1" WH bodylift. Tried a holesaw,
but that seemed like it was going to take forever. Ended up drilling
small holes all the way around groove left from attempting holesaw,
then running holesaw again and finally chiseling out an access hole.
At least body bolt came right out.
Got about this far on the second one, and holesaw jammed up and
drill practically ripped my hand off. Gave up for the night.
