from vw it would be very expensive, but its easily found in scrappies I beleive 90s age SEAT ibiza/toledo one will fit.
the ebay kit is also missing the boot that covers the uj, this is also different. Oh and one of the pipes is missing, looks to be the one between the pump and the reservoir, though this is pretty generic a MK3 one would probably fit, not a pressure hose either so not hard to buy off the shelf.
