The VIN plate should give you all the info you need to reg your type 2. Hope the following info helps you. If you still have problems get in touch with Justcampers and they can get you the VW Birth Certificate of your vehicle.I cant remember what the cost is but they will tell you. Once you have got that send it to the DVLA.
The chassis number, or Vehicle Identification Number (VIN), can be found stamped on an aluminum plate either behind the front seats or in the engine bay. An example chassis number might read: 229 375 250 (This number belongs to a Type 2 Microbus made in 1969)...
The first digit of the chassis number, '2', indicates that this is a Type 2.
The second digit of the VIN, again '2', denotes the vehicle model. Which model do you have?
1. Panel van
2. Microbus 7/9 seater
3. Kombi i.e. van with windows
4. Deluxe microbus 7/9 seater
6. Pickup
7. Crewcab
The third digit of the chassis number represents the year
