Got something done!!  I almost forgot that some parts are easier to make than others,,,  I printed the new wheel hubs. I haven't cleaned them up yet but I made a few with different widths to choose from. 

 I know it's not much but they are a bit more offset. 
And got some Mario feed,,,

Some scrap aluminum handrail pieces I can use and the power supply I hope I can use. It's a transformer for low voltage lighting, outputs 12volts.
