thanks again everyone,
just a bit of info the max length the shock can be is 300mm.
with the bike on the centerstand i disconnected the bottom shock mount and let the back wheel rest on the ground the aluminium lump that the shock and the dog bones attach to  now moves slightly until it hits on the frame near the center stand. the bottom shock hole and the hole in the aluminium lump are now out of line by about 5mm.- in other words 300mm is about the max shock length without major surgery
god i hope that makes sense  one photo would have covered this so much easier
