Kohler Rochelle lift wire 51326 - old style

Reference: http://www.serviceparts.kohler.com/Pdfs/1001336_8.pdf
I'm looking for the lift wire, part 51326, for the old style Kohler Rochelle. It is a long shot, but if someone is rebuilding their toilet and tossing the innards, I'd like to buy the part from them. It's either that, or rebuilding the whole thing, which seems rather wasteful.
