Eibach anti roll bar kit bushes

 Hi guys !!
I have just called eibach up about getting a replacement bush kit for my anti roll bars and have been told that they have discontinued them  Superpro do the correct diameter bushes for the rear - outer/inners and the front inners , but not the outers.  The front outer bush diameter needs to be 20mm where as the max diameter superpro do is 17mm.  I have looked on the powerflex site and they don't do it either.
  Anybody have any ideas on this ? or will the 17mm fit with a bit of elbow grease ?

Cheers !!
