Wanderer: yeah, I noticed that after I posted the pic. I stole the pic from Park Tools' website (at the link I posted), I don't know why they removed the bushing in that link. The part of the pic I'm referring to is the way the outside plates look.
Al1943: the chain measures within tolerances. It's just a basic KMC chain, nothing fancy. I have extra KMC links from other chains. From what I can tell, I'm not really supposed to break and relink a chain, since that removes metal from the pushed end of the rivet. I don't have a removable link laying around, though, that I can replace it with.
