I really wish I could help more, and don't take this the wrong way. But you might want to purchase tanks of a more common scale to have ease of access for parts. I say that because I purchased a tank that I didn't see any replacement parts for it specifically. So if one piece breaks I'm boned. 1/16 and 1/72 are the two most common ratios I've seen with hoards of replacement parts for them. I hope that helps, best of luck mate.
