Spent a couple of hours today and fitted my new drivers seat. Was quite straightforward just used the original runners and mate some mounting adapters from the new seat to the old runners out of a bit of box section, bolted these to the new seat and then to the original mounting studs on the old runners and just quickly welded them to the runners for a bit of extra strength. Just need to get my friendly local auto electrician to sort me out a resistor for the old airbag wiring & job done! Very happy with how this went and the seat feels great!
