use parts from a mk2, 3 or 4 golf. Mk4 golf aluminium ones are best as the older iron ones are notorious for seizing up all the time. But mk4 golf ones are more expensive because they are much more sought after.
You need everything including the stub axles. You will have to make your own handbrake cables though, use motorbike cable solderless nipples and then a cable from a golf.
