Exterior difference

[TurboFource]

Besides the cut down b-pillar/sail panel, are there any exterior body differences between an S2 and a Twin Cam?

[Clifton]

Type 54 S2's have lower headlights.

Lower floors, two vents rather than four in the engine cover, no opening in rear panel, sill covers on the TC/S, larger commemorative badges as the victories piled up, etc

[SwiftDB4]

Isn't the body between door and rear wheels slightly longer on a TC because the wheelbase is 1" more?

[jbcollier]

Yes

[TurboFource]

So the wheelbase increase and lower floor is how the Twin Cam gets more interior room?
