Spare Parts
Sorry to say. You will not find one spare part in Germany for FF04Evo.
Tamiya Germany sucks! The lack of spare parts was the reason, i didn't bought this beautiful kit. Every part has a special order number.
They did the same shit with Evo6MS. Tried to get a spare aluminum lower deck...
You can ask the customer support @Tamiya Germany if they can get the parts from Japan.
Good luck.
