You can't argue with results.
Having been involved with auto body work for years, I've always said the handiest tool in a body shop is a three foot 2X4.
One time I was working on a C60 farm truck that had been dumped on its side. The passenger door had about a 2" gap at the top. I opened the door halfway, with the window down, wrapped a towel around the upper corner of the door, wrapped a chain around the towel, hooked the chain to the corner of the box. Gave one big yank on the bottom of the door and tried it. It fit perfectly.
