i would start looking for cabs, the good thing is you have a TON of options, you can take something hit in the rear and the whole cab will be good, you can take something hit on the driver side, and cut and weld, or you can take something with a light front hit as long as its good from the fire wall back.

i will ask my dad tonight what they do at the shop about cab replacements and vin number legalities, they do a lot of fleet and truck repair, and i know they do a lot of cab swaps
