RC Jeep JK Siderails Rock Slider V1

For my new scale rig (Jeep JK) i made some siderails/rockslider. They should be close to those of the Jeep JK 10 Anniversary Edition.
Mounting points are within those of body (Hong Kong) of the Jeep (Holes must be drilled).
I tried to make them also helpful sliding over the rocks below the body of the model.
