Sharping levers installation

Me and my harp have been parted since early november, so I havn't been able to play it nor install the sharping levers (the "Universal" model from Musickmakers) until now. Today however me and my father started to install them. It's not very hard but still a lot small adjustments to be done, so it takes a while. We will put the final screws in tomorrow. But two of the levers are lost! I have no idea if they didn't send me enough or if they're laying around here somewhere... but I havn't really picked them up until today :/ However I don't think I use to play the two highest strings and if I do I can always re-tune them instead, until I get the missing levers.
