Go ahead any copy anything you'd like. That's why I took photos to share. :thumbsup:
I'm sure the other guys would be able to point you to some good cages, all I can say is 1.75" DOM is the minimum I would use (my rollbar is 2" DOM, but if I added more, it'd be 1.75) and diagonals are your friends. :D
The only thing I regret from the initial install is the lack of a diagonal behind the cab. I left it for phase 2, but phase 2 hasn't happened yet (and it's been a few years now).
