Nate,
I have mine mounted to the original roof mount in the front and to the cowl frame in 2 places on each side.
The back is bolted with 2 bolts to the main seat frame member on each side and rear bagwell 2 bolts through the frame member.
I can pick my cart up by the roll cage but I wouldn't guarantee it wouldn't bend the daylights out of it in a 50mph roll!
I hope I never have to find out!
Jimmy B.
