MP72 model trucks

I'm building an HO MP72 model currently and don't have the wheels to insert on the trucks. Does anyone know what type of wheels I should use?

Thanks

Use an old set of 34 inch plastic wheelsets for testing and make sure the truck is square!
Micro-Mark makes a tool for cleaning up the "cones" the needle point fit into.
