Lionel 2055 Parts Question

Hello,

The rear truck assembly on my postwar Lionel 2055 Hudson came loose, which prevents the wheels in the truck from staying in. Last week we put new carpet in the house, and one of the loose wheels was lost in the process.

Could someone provide me with a diagram of the 2055, or a parts list, or even a part number for the wheel that I lost? Its a little late to have it by Christmas, but I’d like to have it fixed as soon as possible.

The wheel is 671-127.
