Why would you make unwelcome comments about 63 when you do not have a clue about the owner’s aerodynamic priorities, class planning, or cost limitations? Many people cannot even dream about a little beauty like the 63.
I do not know you and do not know whether you have ever built a car, but if you have, you should know one has to start with where they are and do the best they can with what they have.
Suggest you try to be more encouraging especially regarding comments open to new people that may want to post.
It is hard enough to build one of these beasts without useless criticisms; helpful comments are always appreciated by LSR folks.
John.
