Yella - I use the bracket from my Bip on a single seat - just fibreglassed some wood into the underside of the unit to build up the height and screwed it in. Mine is a after market seat so not sure if this would work with a 'proper' one. I just change all the fittings when I need to take a pillion. Whe I looked at the cost to get all the bits, it was more than the seat cost!!
