help with stock height link measurement

Hi guys, so I lowered the rear using this method http://www.wrrdualsport.com/tech-guide/suspension/115-lowering-r2 and now I would like to put my bike back to it's stock height. The problem Is I do not know what that height is because I didn't measure it in advance. Anyone know how far I need to back the linkage out to return it to the correct position?
