I am getting ready to start my flatbed/shorten the wheelbase project. I am torn between cuting the frame or moving the spring hangers. My wheelbase is 133 right now, I am shooting for 115-120. I have see it done both ways. The issues that I see with moving the hangers is figuring out the pinion angles. /forums/images/graemlins/confused.gif The problems I see with cutting the frame is cracking later. /forums/images/graemlins/confused.gif If I cut the frame a friend of mine that extends/shortens truck frames is going to weld it up. He said it should be fine as long as the frame is allowed to twist.
