I wrapped more straps around the door header and 2'x4's that were resting on it. This would help keep it from sliding while I worked it into place. After bracing everywhere I thought might push, pull or bend, I put two wide straps around the end sticking up and wrapped them around the doubled up section of the ceiling joists. I tightened it up a few clicks then went and lifted and blocked up the end closest to the ground. I repeated this process until it fell into place. Whew!!! It might have been easier to build it in place.
