If the bolt going through is the larger 6mm size, I would try Suntour or Simplex pullies. First, though, I would also compare overall width (I think that's about the same). Maybe the Suntour sealed-bearing pullies would thus be a good choice since they have a pretty neutral color and are still found on Ebay for around $22/box(2).
