Has the roof of these vans stayed the same throughout the years or have there been changes made? To clarify, I'm speaking of the roof as it comes from ford factory, not SMB's.
The outer part of the roof has been the same since '92. In '03 the underlying structure was changed a little, which resulted in a new headliner profile, to accommodate more head protection in the main perimeter beams. The factory headliner also changed reading light styles in '03.
