WTB: 90mm or 100mm idler

[sunburst six]

So, here's the deal - I need an "old style" Metco idler pulley to complete my set. If you're wondering what I mean by "old style", check this out...

Old style:

New style:

You'll notice the "old style" has a gray contact surface and orange bearing (vs. the newer style's black on black look)

Thanks.
