I would phone the DVLA and talk to them and I would push for the B plate if possible
because mot is less strict than that for a later vehicle if the DVLA are involved all the way they should have no problems at all. There are so many out there that have been thrown together with stolen parts its mad thats why people on ere get upset. I have a q plate Disco ID and chassis but am wondering what to do with it TBH if anything.
