I bought a set already converted but the dampers knackered after a short while so the kit had to be removed from the dampers and put onto new konis which involved removing the cups and having the collars which go underneith the threaded part made up from the measurements from the old ones as they couldn't be removed from the old dampers (courtesy of 'nthorpey', cheers m8). So to answer your question i dont know where the kit came from, sorry.

Nick, they couldn,t be p/coated as that involves heating the shocks and as they're full of oil it was impossible without emptying them so i just had them painted.
