Yes you will need those parts, it should have the part #'s too. You are probably right about the prices in YEN, but those are list prices so you should be able to do better. Kyosho did the same thing with the RR/EVO. It didn't come with a front diff so you had to buy all the parts. Later they offered a complete kit that was cheeper. I would like to see that manual, I'm sure it will be on Kyoshos site soon.
