I replaced or removed and reinstalled more door regulators than possible to count during my 30 years in auto collision repair and I've got the scars to prove it.
Those inner door assemblies have some of the sharpest metal parts you'll find on a car and unfortunately, you don't find them until you see blood. The ones that are pop riveted in with the 1/4 inch pop rivets are the most challenging.
