Interactive 3D Product Design Modeling

I have two cars in 3D.

Car # 1 is complete but needs a new front bumper bar, rear bumper bar, wheel arches and side skirts

These parts are available from car # 2

I need someone who is experienced in 3D to:

1. Export the front bumper bar from car 2 and add to car # 1
2. Export the rear bumper bar from car 2 and add to car # 1
3. Export the wheel arches from car 2 and add to car # 1
4. Export the side skirts from car 2 and add to car # 1
