Im sure you’ve inspected 100 times but sharing my experience. There is an inside and an outside on the “roll bars” and a little tab on the center piece that should fit in the groove, the notched side should be the “inside” mentioning cause I didn’t see them at first as I was trying to decide if they were exactly the same or different.
I was contemplating not even putting the roll bars on. Not sure the lil guy will generate enough speed to warrant them. More aesthetics than anything.
