Well if money is no object and you want a set for the rear...........VW GOLF MK2 JETTA A2 VOTEX MUD FLAPS REAR NOS 191075101A GL GLX GT GTI 16V G60 | eBay
Can't remember my part numbers now, but be aware there's slightly different versions amongst those available for the later cars .. along the lines of for those with spats / arches like your GTI and others for models that didn't, do look very similar at first glance. Still too rich for my blood, but a front pair here - https://www.ebay.de/itm/15539449570...N1lPzD5H78BcrZ0hWunWJDw38=|tkp:Bk9SR8jZ3YXnYQ Do appear to be for GTI's judging from the packaging blurb, but double check with the seller if you're interested. Unfortunately they olnly list as sending to every country in the world apart from the UK, but doesn't hurt to ask.
