yep I've got em on my MK2. Only problem was I had to grind down the slieve for the front wishbone bush before it would fit on the car! Oh and when fitting the ARB bushes, if they go a funny shape you've overtightened them

As for the beam mounts it depends who you ask, some say that you should always go genuine, but others have their cars on the track regularly and swear by polys.
If you go genuine they need pressing in at a garage, if you go poly its reasonably easy to fit em DIY. If you're canny its possble to do the job without splitting the brake lines too!
