At some of the shadier motorcycle swap meets, you can see all the parts of the same bike scattered out on different vendor's tables.Don't forget that Harleys especially older ones can have 3 VIN's on them. Not a good idea to ride around with some dead guys VIN somewhere on your sled... If you swap out the frame & crank case you should get them all but then you are left with non-matching numbers which may raise red flags...
