1973 VW High top project bus

I found this bus in a field where it had been sitting for 10 years according to the owner. The engine has been removed and the interior is in very rough condition due to deterioration caused by the weather. The 2 burner stove and sink are there. I took it the DMV for a VIN check. but they would do it because it has no engine??? I do have a Bill of Sale and past registrations. I was also told that the VIN has been dropped from the system so a new title would be generated. I think it has the original paint and the body has very little or no rust (California vehicle) I just got a message that stated that this is 1973 not a 72. I'm going by the sticker on the door? I've now had 3 messages that state this is a 1973 so I made some changes. The last registration document states 1972 and the door plate reads 12 72. Thanks for looking and the heads up to all.
