Ur quattro clutch

[Khanlad]

Im at the start of putting my 1982 wr quattro back together. At the moment im at the searching and pricing up parts stage, i know i need a clutch ( it was slipping before it came off the road, ) and was stuggling to find any of the bigger parts supplier that still stocks them. Ive spoken to pete at quattro corner and he tells me he has 2 left after that he cant get them. So my question is what are people using or going to use if an original one is unobtainable?
