I would guess the roof bar option that only applies to the track frame is similar to the ones circled in red below. I can't remember who has the actual welded ones on track frames, the one in the image is a modified city frame, not the actual version the 'roof bars' would match but I think is the same idea.
The dominator headlights don't have turn signals included, the side mirrors that are on the order option list do have, circled in blue above.
