flip it over and the "up" spring on that side should be removed or it goes up WaYYYYYYYYY to fast. but be careful it's a finger accident waiting to happen, just crank it up all the way up once you get it out of the car to relieve some tension to be a bit safer and clamp it down when you remove it.
here it is installed with the door panels off (still thinking of making them on the vacuum former like a 2000 and up car with door locks and opener(door popper)) just like originals mounting and no crank handle.
