I've never seen a step by step set of instructions, that doesn't mean they dont exist some where. I just finished doing my driver's door lock. You should have a special tool to remove the inside door handle and window crank. I believe most of the T-bird dealers sell them. It's not expensive. Yes there are other ways to get them off but this is the best way to do it. You need to remove the insde
door panel. A few screws and I believe 5 snaps,3on the back 2 on the front. Use a screwdriver to locate there exact location. Use a large screwdriver and pry out right at the clip. remove access panel. roll window all the way up. remove the glass rear track. I took out my outside handle. 3 screws hold the inside door latch mech. remove the 3 screws then you can slide off from latch. Now remove the 4 screws holding the lock assy. Some also have a bolt or screw on inside. Have fun
