There are some JOM coilovers on eBay, £164.99 posted a set.

Cheers for the advice people. Was hoping I could crack them off in situ but if its going to be a pure knuckle scraping, back breaking effort and Im going to have to end up removing them to adjust them I minds aswell just buy a replacement set. The nuts and bolts holding them to the hub etc are well rotten too so will have replace all those, seems odd for a VAG car my other one wasnt as bad.
