How do i change the control panel on my coaster to a Ops one?

Thunderhead at Dollywood I've ridden it 275 times in 3 seasons!

1.King da Ka (front row because you just kinda dangle over the edge!)
2.The Voyage
3.Tennessee Tornado
4.The Legend
5.Thunderhead

Also King da Ka in New Jersey- I love the speed and the climb and drop of the arch is AMAZING.

The Voyage- I love all the drops and sharp turns.
