Shell Valley has NO affiliation with "Shelby American", anyone can buy a "Shelby" vin plate at any number of places and bolt/rivet it on to their car. How one feels about it is entirely up to them...I am perfectly fine with people looking at the one in my car that says Contemporary Classics and knowing the car is a fake
As for the 4 speed, the originals came with one, my replica has one, most of the people trying to make a "real" faithful replica have one....on the other hand, I wish mine was a 5 speed, and the one thing the purist's seem to be willing to avert their eyes from and (sometimes begrudgingly) accept is a 5 speed transmission, if for no other reason than it makes sense....
edit: Motorhead beat me to it.
