Dave thats brilliant thanks very much, it is actually for a good friend of mine who, fuelled by my enthusiasm for my hot rodded 500 and my constant cajoling, foolishly bought himself a restoration project.
Some of his faculties have remained so at the moment he is working on the body, converting to a rack and pinion (one of the best things I did to my 500) and building up a tuned aircooled.
He would be happy to pay for it, perhaps if you come over for the Brooklands event he can buy you a drink.
