I don't know the answer for sure... At some point in the 90's castings were made of the B car emitter, one of which was on the A car for quite a while. Those castings are also smooth. It seems to have happened sometime shortly after filming which was when Ohrberg had the A car and some of the B car remains, so that would make sense from a timeline standpoint.
