Check the runners between a series two and a frst mate. I think they will be different.

There was a whole interior on ft.com in the same 2i option trim that were for sale for £150.
Its a shame that you havent got the rear bench as theyd make a nice interior. Perhaps if you advertise them on fiestaclub of greatbritain or the xroc or fiestaturbo.com then someone who has the boring 2i front seats would snap em off ya as thease would match i think....
