I am afraid there might be a language barrier problem here?
Do you actually mean tracks? "Chenilles" in French?
I think "cadenas" in Spanish translates into "tracks" as well as "chains".
There is this famous Venezuelan modelling website "Ruedas y Cadenas" which means "Wheels & Tracks".
If you are indeed looking for Conqueror tracks I think your best bet would be to contact Accurate Armour, they have a few Conqueror based kits and would probably be willing to sell you tracks separately if you ask them nicely!
You can reach them at
