Mine is a Stroud - Bob walked me through the template process. Another one of those few companies that "get it".
Mine is bolted to the inside of the cage at the bottom on the rectangular rocker panel reinforcement bar . . .
A suggestion - will likely make your fit better -
Get the top hardware and buckles welded in before you measure. Once those are in place, you can better size the height and width, and end up with a nice, taught net.
