9 am would be fine.
I looked at my car, looks like two screw mount connections on each side, one large ram on drivers side and one small ram on each side. you may be able to disconnect the rams and leave attached to the car and disconnect just the top mechanicals. Not sure until we start taking it apart. Looks like someone in the forum would have done this before. A little guideance would go a long way toward success.
I went and looked again, there is another ram on the driver's side that goes toward the rear and bottom of trunk floor. looks like it controls the cables that go to the little flap(wings) that come down with the cover. may be able to disconnect and not remove from car. Looks like the sensors just plug in with a connector.
