My doors are completely stripped of hardware and repainted. When I disasembled them... I had the doors off, on a bench... inside facing down. Needless to say, even with the doors in that position it was not very easy to get all the mechanisms out. I was wondering if anyone as a great way to re-install all the parts i.e. glass, elec. windows, locks ect without damaging paint??? Thanks, Muddy
