hanging unloaded doors?

I don't know how many of these folk have hung doors before but I will tell you from recent experience that hanging a unloaded door will not align properly once complete! The weight really isn't as much of an issue. The vent glass will be the real issue! I cut my doors in off the car bare and hung them after cutting in the jambs. Added the glass, regulator and other hardware. As soon as I adjusted the vent window frame and tightened the allen bolt inside the door and tried to shut the door it was all out of wack!! These doors are flemsy as hell without the allen bolt in place for the vent window frame!

Also be sure to have the car down on its suspension too! I had mine up on jackstands and that screwed the alignment up as soon as I removed the stands.
