It's just a standard Pyoneer roof, and the pillars are where they are supposed to be (on the Pyoneer body anyway). If look is what First was worried about, they would have sent it back to Falkirk for a new roof - which is obviously a bit more expensive.
That body, EL2000, has ceased production since 1996. ELC wouldn't have the jigs and tools to do that. Even if they had, it would be an expensive thing to build it as a one-off anyway - which was not what First was looking for in the first place.
