I have replaced the Warthog's Horn with a sentinel beam, and changed the sentinel beam's hlmt to the MLX. Then I nulled out all of the Warthog's shaders, except for the tires (which are going to be used for the MLX tires). I also nulled out the MLX's shaders for its wheels so they don't show up.
But, my problem is that the MLX body is too high up, and it does not line up with the warthog wheels.
How can I move the warthog's weapon (the sentinel beam) so that the mlx body can be lowered to line up with the wheels of the hog?

And if there is another program besides Entity that allows you to do this, please say the name of it. Thank You
