[THI]

Not sure how Oregon law works, I do know a body shop that would put a new to the truck cab on a frame here in Michigan and put the original VIN tag on the new cab - this had to be done under the supervision of the MI State Police since the frame is actually what is titled. The proper rivets were provided by the State Police and they had to observe the tag being attached along with the cab being mounted to the frame. If their procedure was followed the original title stood clean.

What usually happens is someone puts a cab on a frame then sells based on the body and not the frame. Used to see a lot of mid 1970's 3/4-ton 4WD trucks for sale with a 1980's 1/2-ton 2WD title. Not usually a problem in Michigan because there are no smog checks (used to have them in Detroit and suburbs). If I were to purchase something like that, agree with the above statement of wanting to know the person who did the work or a great price.
