I don't know if there is a frame number or not. The ID tag is normally on the drivers side front door post. If your engine number still matches the title you are in pretty good shape. You will be able to register it anyway, its will just depend on how many hoops you have to jump thru. My California native truck had its 1952 216 replaced with a 1953. I had to take the truck to the Highway Patrol of their verification since it was out of the system after sitting 24 years. A real test of patience ensued. I had documentation I got via this forum that showed the original ID number issued to the truck was a 1952 216 engine number. It also showed the engine in the truck to be a 1953 engine. The door ID tag information identified the truck as a 1952 and even the date and location of production. I had a maintenance log for all work done to the truck, including the engine change. I had the pink slip (with the old engine number) and last registration. The Highway Patrol drone would not even look at any thing I had, even after repeated requests. He indicated the door tag did not match the pinkslip. I tried to convince him they used the engine number and things deteriorated. When he finally looked at the engine he told me there were not enough numbers according to his book. I was as (frustrated) as he seemed to be by then and told him he was wrong. Said he would research it and wanted to know exactly where the truck would be parked. Two weeks later the CHP office called and said I could pickup my papers- everything was in order. No explanation of the delay or indication their info was wrong.

So I am sure you can get it done. I just hope you have a better experience than I did.
