What is the general view on these valances? Are they period for a 1936 replica? Are they just for Supersport/V6 performance related cars or is it a case of "if you want one get one"?
The Trad Morgan is not a 1936 replica, it's a current production car that just happens to look the same as it did 80 years ago

As for front valances, very definitely if you want one, get one. Anybody who suggests that there is a way that your car ought to look should be ridiculed and ignored.
