Request for Dagu Wild Thumper wheel pics

I found that the Dagu wheels used on the WT chassis would be awesome for one of my projects:

They are almost 5" in diameter, knobby, and have a sweet red anodized finish. All the trappings of perfection in my eyes. Anyhow, the hub is my concern. I have a 6mm shaft I want to stuff in its hole but I don't think it will jive. There is a 4mm shaft adapter available but it doesn't look like I can easily modify it to make it work for me.

If anyone has hi-res pics of the hub (both sides) so I can contemplate an adapter, or if you have ideas on how to make this jive I'd love your responses. Thanks.

not sure if this helps

Claudia works for DAGU and oddbot probablly know them better thann anyone else here.

not the greatest resolution

The outer diameter is 10 mm. Seems like enough material to resize te inner diameter from 4mm to 6 mm. The screw holding it tight (M3?) might lose one or two threads though. May no longer be as strong.
