The black bar is the only thing that attaches to the ceiling. They make one that is for a open rafter ceiling that does not have the support bar. The spacing between the lift points is critical for the correct pick.
The straps are the secondary lifing point, the primary picks are the front and rear lifts. You release the top (front screws and back pin release) then slip a rolled towel under each side , attach the front and rear lift points. I then lifted each side just enough to slip the straps over the pins. One person can lift corners or front by himself. First time I picked, I did not have the top level (front to back) and I had to set down on supports and level the lifting bar before I could reinstall on the car. If you have additional questions, e-mail me and I will give you my phone and we can talk about the lift.
