Lost footage?

I just watched the original trailer for this movie, and I noticed some clips in it that appeared to be from scenes not in the released film. There was a shot of Barb on her motorbike, taken from behind as she rides it out of a garage into the dark. She seems to be wearing her long leather coat, so I assume it's from just before the "hooker" scene. There's also another brief shot of her leaning out of a doorway. Does anyone know where I can find deleted footage from this movie? Thanks.
