Thanks Geoff, Yep I've got hold of one from Duncan, off his Disco scrapper as suggested. The basic body, plugs etc are identical. The only difference I can see is that the spindle is different where it goes through the door. I'll have a look tonight and see if I can make it fit.
I've also got some humungeous leather seats from a Volvo. If I can make them fit it will be seriously comfy ! First impression is that they might be a bit wide.
