This cab is located at a friend's place 140 miles from where I live so I can not look at it for a week or so to answer any specific questions you might have. I bought it several years ago and recall that it has no or at the most very little rusted out sheet metal in it anywhere.
The loose hood shown inside the cab is not included. There is a large dent in the left rear corner of the cab that is not shown clearly in any of these photos. The metal check strap in the left or driver's door is broken or missing.That let that door fly open so that the bottom of the door hit the outer part of the fender and put a small dent in the bottom of that door. The right hand or passenger's door most likely has experienced the same problem. I believe that neither of the doors is rusted out anywhere. If you need the frame and or front axle assembly or front wheels, I will list them after I have removed the cab. I can supply a good open Montana title if need be.
They typically take about 8 weeks to obtain from the Motor Vehicle Department in Helena Montana. I will have a lot more and better photos in a week or so.
