By definition,Vincents are out(not rigid),an ohv BS will cost five to six figures,(some not rigid either),all that could be considered is a rigid Thunderbird,or a sq4.Now as the gent is a newby,classic wise,I assume he wont want to spend forty years searching for parts on fleabay.Buy a rigid pan in the US,if necessary,and ship it back.He will be able to buy any part of any year pan(or any other HD)from numerous suppliers in the states.He can even buy a replica,new made for less than $20000.(Depending on the law where he lives,he may have to ride it on trade plates.).How many pricey Broughs,Internationals,Sq4s,Gold Stars and Vincents are horrible bodges, very pretty,but R/S mechanically.Ive seen a few,that have made the new owners cry.So there you have it.I have only fifty years experience,so I don't know as much as most young blokes and I should probably keep quiet.Regards John.
