I tried to find some aftermarket 1/48 tracks but it appears my search is 6 or 8 years late. My solution was to buy the Tamiya kit, but that didn't work out so well because I goofed and ordered a 1/35 kit by mistake, and therefore had to also get a HobbyBoss 1/48 kit. Those tracks are much better than the rubbery plastic in the Bandai kit, plus I got a box full of spare parts to work with. Billions of spare parts as the HobbyBoss kit is much more complex than seems necessary. Probably the whole kit didn't cost any more than the resin tracks that are no longer in production, either. So far I have used the seats that suspend from the turret on the Bandai kit, and there are some compressed air tanks that also will find there way in never to be seen again. I have the drive train all in, painted and dirtied up some.
