Here's a little trick I thought might come in handy for someone. Both the lower door frames and lower hinge pockets were all but gone on the cab I refer to as the good cab. I removed and modified an upper hinge pocked from the opposite upper side of the practice cab and modified it to become a replacement for the lower pocket on the driver's side. My other lower pocket is not quite so bad so I may be able to save it.
