i picked those seats up for £30 from my local scrapyard and were dead easy to make fit.. i even used 2 of the original bolt holes on the tunnel.. just had to bend the tabs down to 90 degrees on the front of the tunnel and move one over slighty and reweld.. the back left hand tab (if sat in drivers seat) was just pulled abit further down and drilled through and bolted onto the tunnel and the back right i got a piece of Angle iron wleded a top onto it with a bolt going through it.. wleded it to the chair and drilled the floor for the bolt to go through...job done 
£30? Wicked.
I'm going back to my local scrappy tomorrow for the ones I spotted last week.
Funny isn't it, its not a massive amount of work to change them, but if they were MPI seats they'd be £300
