The Rampage half top is just like the OEM soft top from the windshield back to the first bow. (except that the windshield footman loop is used with a strap like a bikini top)
The spreader bars from the first bow to the second bow are not used.
The second bow is slid forward right behind the roll bar, the top rests on the bows and not the roll bar, just like an OEM soft top(see pic at top of thread).
There are straps & buckles to secure the second bow to the roll bar .
Two footman loops are provided to secure the rear window to the floor and straps attach the lower window to the roll bar.
The package is basically three pieces:
A rear deck cover that uses the soft top belt rail system and snaps to rear window.
A plastic rear window that zips onto the half top.
A half top that mimics the OEM soft top using your own soft upper doors with OEM square corners and small usage of the belt rail system just past the doors.
