here is a simple way to tell what top you have. there are 2 basic types, best top and OEM or OEM replacement. Do you have velcrow anywhere (around the Door). if so this is a best top. if not this is a OEM. The frame around the door, is it a bent rod or streight 2.5" wide peices? if it is bent rod its a best top.
and if you can get it on the jeep with the hard doors, its a best top. you are missing the hardware that bolts to the windshild at the spreader bar bolts in the top corner. this gives you a place to insert that round rod. then you can insert the rod to the plate on the body tub near the door latch.
about the back, im not sure what you are refering to. sorry.
Its not what you buy...its what you BUILD!!!
