Just picked up a 7.0 T-90 today, it came with metal tracks, metal idlers, swing arms, and sprockets. I started looking for a few items, e.g. sub-frame for the hull, and metal road wheels. Maybe I am just blind, couldn't find any metal rollers, by themselves or with the road wheels. And it also seems that most road wheel sets I have seen come with metal swing arms but no springs, Does anyone sell just the metal road wheels with bearings in a set for this model? I wouldn't;t know what to do with another 6 pairs of metal swing arms.
