If u dont mind abit of hard graff, swap the to backs around.
1. remove the seat covers ( roll the seats as far foward as they can go, then u'll c sum metal clip, type tings cut them with a side cutters then remove covers).
2.at the bottom edge on either side u'll c sum bolts undo them (cnt member the size 17mm I think??) then the seat will cum apart
3. swap em over then follow steps one and 1&2 again ( the clips that hold the covers on are called hog ring, u need to buy sum, and a hog ring tool to put them on).
hope this helps, I a trimmer so I know this works 4 a fact.
