I found links for the front anti-roll bar on e-bay they are for aToyota Celica
Item number: 4542114560
I bought a couple and they fitted pretty good just needed a washer on the wishbone to make room for the nut.
I also noticed that Merlin motorsport do anti roll bar clamps which are basically a hydraulic pipe clamp, so if you go down to your local hydraulic engineering company you should get them a lot cheaper.
I got a pack of 5 from RS Components including mount plates, top plates and bolts for less than a tenner.
I did have to make a plate to mount them on to the chassis

I put on 2 at each side which is the same width as the original bmw rubber but may prove to be too hard but it will be easy enough to remove 1.They may wear out quicker than rubber but at 10 quid a time I'll live with that.
I have photos of the above but haven't a clue how to post them
