Well I've took the plunge and brought a set of Mark 2 Ghia X seats in Alchemy for £80 all in, not the tidiest set in the world but I only want the Drivers Front Seat frame as the one in my ST200 is broken. So fingers crossed the Side Airbags fit, although I think they were an option on the early cars so the mountinmg points should be there. Should make an interesting build with the 10 way adjustment, glad I work for a seating company lol. Now to figure out what to do with the rest of the bits........
