If you order it from the factory with dual tops, the roll bar brackets are already installed. In fact, so is the body of the soft top. All you would have to do is, remove the hard to and install the door surrounds. Then raise the soft top and install the windows. The only othe step is to put the tailgate bar and brackets in.
The initial install/turn over will take a little time, but as others have already stated, it does get easier with practice.
