Good luck finding them, I haven't see those around in a while. I had a set like half a year ago but they are gone. I just texted the guy who bought them to see if he switched up his setup and felt like sellin them, so we'll see what he says.
Oh, missed that part. OP if you only need one, then you're better off finding one at a junk/pullapart, or just bitin the bullet and buying a new one. Doubtful that you'd find one here.
