Hello I'm new to all this so your help and advice would be helpful . I have a 1969 series 11a which I brought as a non runner , I want this to be a hard working usable landy . The petrol engine is shot to bits so I want to put in a TDi 2.5 but I want it to stay as a historic vehicle how do I go about this with dvla ??? Thanks for your help Lollie
