Hi Sir-Bastion, sadly I wasn't given the option of the hardtop as it was gone before I got hold of the car. I would have kept and remade it. The diesel is a 2 litre of the correct vintage and type but the cars numbers suggest that it was fitted with the petrol when made. The cars wiring also confirm this. It was wired with entirely blue and yellow with a few odd wires from the original loom. Chhers, Paul.
