To Go Wing or not?

Thinking of putting the Go Wing on my 71 Dodge Demon. Didn't come from the factory with one. If I go ahead with it, is there somewhere I can get info on measurements for exactly where it goes & the modifications I have to do inside the trunk.

Here is mine, original J81 car with the center rib on the trunk. (Late build, 07/09)
