Perhaps someone on Shapeways can be persuaded. The sideframes would need to be designed for use with nylon bearing inserts to prevent the axle from wallowing out.

Thank you for the information. I looked over those trucks and agree that they appear to be the best option. I found a seller and ebay and they're headed my way.
For some reason the pictures didn't come through to my email and I can't find your reply on the IO page.
