Bachmann #26565 1:48 Scale On30 Narrow Gauge spares

[collectors]

Hi, i hope you can help?. I have had an accident with my Bachmann #26565 1:48 Scale On30 Narrow Gauge caboose & i am trying to find what wheels & couplings fit this model by part number & cant find a blown up diagram with part numbers for this particular model. Or just the part numbers would be great.

Thanks
