I can’t find the arms for constructor so I decided to try to find a way to connect combiner wars devastator’s arms instead. So far no luck. Anyone got any ideas?
Try Shapeways. Several sellers make connectors to attach different types of Combiners. You might find one to help you. Combiner Wars joint(CW female joint and 5mm peg) by chanponman on Shapeways This one allows non Combiner toys to combine with Combiner Wars limbs for example.
