Most of the stuff swaps straight over - seat hinge, lights, seat catch - I did mine at the weekend.

Dual seats are pretty easy to come by as people usually want the single seat. Just make sure you get one as complete as possible and then just swap across the bits you need.

A good tip is to mark on the two-part seat catch and light brackets where they line up for each seat, as I spent ages getting this just right!
