I always jack my stock bumper directly under where it bolts to the frame. No bending, however it does pust the back of the bumper up a bit. Just get on the bumper when done and jump on it a couple of times and it will go back down. For the front, I have a custom bumper. I can jack pretty much where I want on that.

I just want to tell you both good luck, and we're all counting on you.
