Hi, I eventually found some nice leather s type seats to replace the older seats in my 1998 car. They fit in well, but the old ones bolted through the floor chassis members, and the bolt positions are completely different. I want to fit the new seats correctly, and if possible, without drilling too many holes, so that the originals could be refitted if somebody wanted to. If anyone has done this, I would be grateful for advice. Many thanks, Paul.
