Using a custom model as an Actor Blueprint?

I’m following a basic vehicle and suspension tutorial. I have a flattened cube as the actor with 4 wheels as suspension, If I wanted to use a self made model how would I replace the cube with my own model? I hope that makes sense. Following this tut: UE4 Car Vehicle Wheel with Suspension using Physics in Unreal Engine 4 Tutorial How To - YouTube

You would first create the model, then rig it appropriately.
If you aren’t using the adv. techniques, then really all you need in essence is the Root bone, and the 4 wheel bones.

Once you export the FBX and import it to the engine as skeletal, you can then replace or create a new BP for the vehicle.

I see, thanks.
