Well, Alan, as one of those guys "back in the day", it was usually because you were a flat rate guy and that was the quickest way to repair it. We used to also weld shims on to pull. Personally, I welded the holes in the edges because you were begging to have the "salve" come off otherwise and my conscience required it. Don't forget, these were cars that were starting to rot when 2 years old and nobody ever thought they'd be around today. Mea culpa
