just change the details and ie engine number, capacity etc, and you will get the v5 back all sorted, I did this with my 100E,
If you ask too many questions to them, you may have to go down the points system to keep the id,think you need 8 points to keep the id, 5 for the shell then it's 3 points each for the front and rear axels engine ,trans etc.

so tell them the min they need to know!
