I got them for $550 from a Honda Dealership, they took them out of their Si project car, and they are VERY comfortable. I have been away all weekend so I hope to start trying to get them in this week. I feel kind of stupid sitting in them while they are on my garage floor.

 

If all else fails then there is a technique to swap the seat pans on the bottoms so the rails are exact. This is what I was going to do to my Del Sol when the S2000 seats were in them. Before that was done, the seats would only sit on three mounting areas.
