I have no idea on that--every state has it's own rules as far as issuing or re-issuing titles and VIN numbers...(and it seems every RMV cop has a different interpretation of the laws too!)...
It might not even be possible to get an "original" title for that cab,the only way you might would be to track down the last owner that had it registered and see if they would allow you to apply for a lost title in their name and pay for the fee--even then,without a VIN tag,if you ever get pulled over and they see it missing or a home made one in it's place,things could get dicey..
It might be possible to get a "salvage" title or have a new VIN issued as a "custom" build maybe...either of those will kill resale value a lot,if that is a potential problem...
A few guys I know have bought rust free un-titled cabs and swapped them onto their trucks,and they just re-used the VIN and title off the original cab--which is technically "illegal",but they have not had any troubles either--they usually dont inspect old vehicles that closely here --as long as the title matches the VIN and it's properly registered,not reported stolen,chances are no one but the owner would ever know the cab was swapped..
