finally got the seat sorted, the aftermarket manx seat proved a 'mare to fit, the fixing screws on the seat base are glassed in at all different angles proving nigh on impossible to bolt to the welded in seat rails on the subframe, the ally mounting pillars that we made proved a waste of time, i ended up cutting them in 'third's and milling them to shape to make a sort of spherical bearing to square them up, bastard of a job, the sort of thing that rob's you of vital hours but something that just has to be done.....
