Here is the C-clip that holds the window and door handles to the door panels. Using a screwdriver, they can be pushed off their perch on the handle's backside. | 
The window crank can be left alone; however, the door handle crank internals need to be removed. | 
The handle is connected to the door latch via a metal rod; therefore, the entire assembly needs to be removed. To remove the door latch, you must remove the three screws that hold the latch to the door. Before I removed the screws, I hit them with a hammer and a screwdriver to shake off almost 40 years of being seized up; that way the screws won't strip. |
I could then remove the latch/handle setup. | 
On the inside of the doorskin are two nuts that hold the handle to the door. Remove them and the handle is free. The key lock just pushes out. | 
The rear window runner needs to be removed as well. |
Because the handles are going to be shaved, there is no need for door locks anymore. To remove the lock, the first step is to ditch the lock rod. | 
This is the door lock lever on the door latch assembly. The only way to make sure the door never locks and your hand doesn't have to find its way through a window is to remove the lock lever. | 
The lever is held on by one rivet on the backside. Grind the rivet off and the latch pulls right off. |
