My father's business partner was a US Army rebuilding depot supervisor in Belgium who took wrecked and battle damaged military trucks down to a bare frame, straightened and reassembled them, and sent them back to fight during WW II. After the war, he and Dad spent 20-something years running a general auto shop, where he did the frame and wheel alignment work, and Dd supervised a crew of mechanics who did everything else. That guy could have straightened out a pretzel without changing its flavor or texture. Fixing a slightly tweaked stovebolt frame would have been child's play for him!
