I.m not sure what for you need the aftermarket tracks for the tank. I would say the Trumpeter made them OK. But if you want to play a little bit with them you may use the SkIf plastic set or the Trumpeter..
Don't get me wrong, these tracks to the T-62 are fine, just wanted to play with a aftermarket set, see what's what, as it's a fair few different ways to attach them to each other....
