Well, dang. Did a quick hang on the driver’s door just to see how it fit and this is what I found....
Looks like I’ve got the opposite problem over here, which would tell me the back of my cab is shifted about an eighth of an inch to the passenger side.
Here’s how it looked when I pulled out the pillar to simulate shimming it.
A few questions with how to proceed:
Should I get the cab on the frame to ensure there isn’t a twist in the floor causing this?
Could I get away with shimming the driver side B pillar and cutting out a little of the passenger side B pillar to get the door holes correct without cutting the rear of the cab loose from the floor?
I think I will have to get a new driver door due to rot in and around the lower hinge area and in the skin around the front and rear window posts. Should I wait on getting one or both doors before proceeding?
Were these door ever shimmed between the A pillar and the hinge? Did Chevy ever do that to adjust how the door fit top to bottom?
