Andrew, the vast majority of original 427 Cobras were produced as roadsters, so no side pipes, street dash with glovebox, and token bumpers front and rear.

The vast majority of Cobra 427 replicas are produced as S/C clones, so the replica 427 roadster is very rare. If you want it to look like an authentic original, that would be the one to go for, and then you get the street dash and glovebox. If you decided to add sidepipes to a roadster without trying to turn it into a S/C clone, that would certainly not be frowned on.

In the end, it's really what you want to do that matters. Bear in mind that most people think that a Cobra is an MG or some other British sportscar, particularly here in Aus. where Cobras are so rare.
