9. When we began this project, James told us that most trucks are not dimensionally identical, so building a bumper with a tape measure and level would yield a crooked bumper once it was all finished. He was right; when we checked this Tundra, one framerail was higher off the ground than the other one, and that's with a stock suspension. James did use a measuring tape to measure the bends he made with the tubing bender. By measuring the hydraulic cylinder piston's extended length each time he made a bend, he could easily repeat the bend on the opposite end of the tubing.
