Anyone out there who has replaced a cab? My early '01 has serious rust issues, discovered the cab mounts are about gone, one of them is holding nothing. Engine is perfect, 419,000 miles and doesn't use any oil. Would like to find a clean rust free cab and fenders to drop on my frame. I'm not a mechanic, and can't tie up my shop space to do the job. Anyone out there do this for a living? This has been a great truck, and I hate to give up on a perfectly good Cummins that gets better mileage than the new trucks. Thanks!
