CSW Anti roll bar weirdness

Hi All

Ive searched but not found a conclusive answer... I have a 2000 (w plate) 110 CSW td5 as its mostly used on tarmac anti roll bars seemed a good idea, picked a pair up of t'internet.
All the clamps bushes etc look good except the clamps only have two bolt holes. The front mounts on the chassis has four, I can get 4 hole clamps but they're specified for rears only. As the bars are different diameters I guess the bushes are matched as well (front in much bigiger dia - i assume thats to compensate for the weight of the engine) Is that a problem can I just use rear clamps on the front? And as they appear to be m8 holes are they supposed to have shouldered bolts as appear on some diags, and ive seen td5 bushes (brit-car.co.uk) but all the bars appear are the same so whats the difference in the bushes. Dead confused now

clamps for front do have 4 bolts bar should be ntc6837 ,brackets ntc6776 ,and bush ntc6828, rear bars for, the 2 bolt clamps would be rear brackets,rear bars and brackets etc are different between 90 and 110 and for td5 110 you need bar anr4344,bracket 592773 and bush nrc5674

thanks james I'll get googling on those. Any idea what the actaul differences are between the bars clamps and bushes? I can only find 1 4hole clamp surely they didnt make more than one and they fit it to front or rear as required. But does it really matter, anti roll bars seem pretty optional and, for example the Britpart kit seems to be a universal one size fits all, what so special about the TD5 110 rear?
Thanks
