Don, I did what I think it best, and ignored the instructions, fabricated my own angle bracket from stock steel bar strap and made sure 1) It looked good on the outside of the car, 2) was structural direct to the frame. You could lift the rear of my car with the quick jacks. Anyhow, I would start by making sure it looks great, that's about all it should ever be used for, hopefully! Good Luck!
