Title a car with no VIN?

Hello, I recently bought a 1965 Barracuda parts car for cheap. It's mostly complete and I was going to use the quarter panels and spare tire well from it for another 65 that I am going to turn into a daily driver. Well after looking over the car I can't tear into. It's got really good bones and in pretty good shape and I hate to remove it from the world to scavenge some sheet metal and a few trim parts. The problem is I bought it with a bill of sale only for parts and someone over the years has removed the VIN tag. As I understand it a 1965 doesn't have the VIN stamped anywhere else. It does have a fender tag with a sequence number that matches the radiator support. So my questions are

1. Is there any way to find out what the VIN was from the sequence number?

2. Has anyone in Oregon gone through the process to get a new VIN assigned and obtain a title for a car with no existing VIN? Is this possible? Was the process really painful?

I'd love to save this car and drop a 360 in there to have a fun car to complement the slant six grocery getter sibling. Thank you.
