The composite chassis frame is identical between the 2wd and 4wd version. The 4wd however, is delivered with the under gearbox plastic shim.
The alu chassis part is similar but different. The 2wd has more front kick-up and has multiple mounting holes to be able to position the servo in different positions longitudinally in the car.
Regarding servo mounting I always position everything in the car loosely tightened so that everything is positioned correctly before I tighten down the screws between the servo mount and the servo ears. I stick to this practice in any car since there are some differences regarding size between different servo makes.
Hope this helps.
