3d rotation on t2dShape3d

I'v got a 3d shape loaded in TGB which rotate around the x-axis to get it oriented right.

Now I need to rotate the object around the axis ( this is so I can direct the players ship according to the heading).

I know that I need to generate a z-axis rotation matrix, but I have never done it in torque and I would appreciate if someone would show me how.

Thanks
