Yeah Ive done it my mk3, just bought the brakets and plates from the my local dealer which cost about ?30, I then took the rear bench out. Got the material off (Just clips off) then fitted the plates. put everything back together and and the carefully with a sharp knife cut a hole where the holes in the padding are and put the brakets in. I then waited until someone on ebay was selling either some Golf GL or vr6 interior came up for sale. luckly a full black GL interior came up and he couldnt sell it so I e-mailed him and asked if I could buy just the rear headrests, he agreed and sent them me for ?20. Im just after some black material for one of the headrests (already had some black material for the other) now to match the GTI interior. very easy to fit any questions just ask....
