on youtube ANDYs auto does a great video covering lowering an obs. Included is front drop for springs, flip kit, notch and a couple other keys i think but as for the flip kit and notch it is a great video. about halfway through they start the flip. With mine i did not take the bed off. i just unbolted the leafs, and picked them up over the rear brakes then set them under, used a lot of man power on the floor jack and moving around jack stands.
