Hi folks, I nabbed a Red Caboose auto rack off ebay and it arrived today. It looks fantastic. Unfortunately, the wheels are too large for Code 55 track. It's riding on the ties. So, I need to replace the wheels with some low-profile flange wheels, but this is an area I've yet to get into. Any advice on what exactly I should be looking for? Are wheels typically universal, like if I buy a lot of a particular low-profile set, I'll be able to use them on pretty much any rolling stock I have/buy? Thinking I may wanna go with some metal wheels too for block detection purposes. Thanks for any tips.
