Reassembling the door is the reverse of disassembly except for one detail. You will need to drill a new hole for the sheetmetal screw that runs between the doorframes, through a hole in the vent window support (if needed), and into the lip of the new doorskin. Once the door has been fully assembled, check for proper alignment. In some cases, the door may sag a little more because of the hardware and glass weight. Adjust your door, and you're ready for final bodywork and paint.
