I have an A700L that I was thinking of upgrading with parts from the A700L2. The biggest difference I can see with the A700L2 is that it has a new C01L2 chassis, GD2-S gear diff, and MM2 motor mount. Is it a straight forward swapping of parts to mount the new parts to my car? Or are there other pieces I'm missing that I'll need to fit the new parts?
