It may be the angle of the yellow car... it's hard for me to see any real differences. I may be mistaken, but some of the flares I believe, are added to an existing rear deck. If that's the case, it may be that the installation would account for any variations. Are Fran's, part of a complete rear shell mold or are the ones he supplies also added to an existing deck, cost effectiveness would make me think they are additions.
