I'm using Epytec VR6 mounts which are different to the standard 1.8t swap mounts - they move the gearbox/engine position to the drivers side by approximately 50mm. Their driveshafts are 500 quid and they have already messed me about, so I'm gonna find a local fabricators. Before I go ordering some up... is there anything I should bear in mind? I've not done this before! Do VW have a specific spline type - how do you spec that? I should measure the gap between the cup and the hub at ride height I know, but how do i get it accurate and how accurate? 1mm+/-?? I'm using '02A' cups, on an FBL 02J gearbox.
