Drivers Seat or just the Back rest WANTED For my 2004 Terrano 2.7 TD LWB

[desgt6]

Hi, I need a replacement Drivers Seat or just the Back rest, due to it having broken on the Internal frame and appears to have been welded previously ? and is all twisted and does not look as if it can be repaired !

I have it proped up from the Back so I can use it, but this very uncomfortable as I am recovering from a slipped Disc !

Does any one have a spare, or know the best place to get one ?

Thanks
Des
