Where can I get hard plastic, resin, or photo etched tracks for some of the former east block 1/72 armor kits? I'm specifically interested in the Skif/UM T-26 and the PST KV series tanks. The PST kit is good, except short on fine detail including the plastic tracks. The UM kit has its own photo etched parts that realle enhance the detail, but the tracks are those soft plastic 'rubber band' tracks and suck pretty bad.
