Master Club from Russia sells a line of resin track links . They have KV-1/KV-2 Track links for about 30.00 plus shipping . They are great and very easy to put together . All you have to do is clean a small amount of flash and drill out the holes and insert pins . They are workable and no glue is needed . Although i used instant glue on mine only due to using a oversized drill bit . Even with that mishap they still were workable and actually worked out better . It's not a well known company , but they are really nice! They do take some time to install , but the wait is worth it . Here is a pic of my KV-II with the tracks unpainted . They are also the same set for the KV-I
Here is a link were i just ordred a set for my T-55
