I've watched this 10 times and I still don't know what happened.....

No need to apologize. Cool video and aren't all Boobtube videos amateur??
a well known dragracer and tuner (many of you would recognize his name, spit the whole rear end assembly out here in Tulsa one time. He`s no dumb ***, just wasn`t a welder back then , I guess. I would bet he is now tho.
