Just skimming those threads it seems the consensus is that it is an obscure but available part (does that make any sense?), but most bike shops should have a replacement. Some people say that their replacement was beefier than the stock piece, so there must be different replacement types out there.
www.aebike.com and
www.loosescrews.com both have good prices and a good selection of little parts if you find the model # or measurements of your part.
I'm sorry that I can't give you an exact link to where you can buy the part online.
