hello i've downloaded the instructions to mount lock seat sip art. nº31040000 and there is a thing i can't understand!!? picture 6 what's the use of this aluminium plate?? my seat is the midle one on picture 8. the distance in the aluminium plate does not correspond to any distance of holes in the seat or in the bike?? is that piece only for the other 2 model's??
about the cushion! art. nº31031200 there is no instructions for this! just say's to screw it on!!?
so i have to drill the seat! that's ok in the vertical ,but there is one screw in the back horizontal!
should i drill a hole horizontaly and then cut the inside of the seat so i can screw it on??
please help! thank's
