First the bolts on Ebay don't mount the top to the car, they attach the two struts in the rear... there are there bolts per side and as mentioned the hole in the top frame is oversized & you could adjust the fop there but you aren't supposed to... There are two 1/2" holes in each side that go through the top frame an the structure that it mounts to, you slide alignment pins through those holes while you bolt the top on.... There should also be a series of T bolts around the rear body that secure the three tack strips to the top well... Once the top well is secure the well liner snaps onto the other side of the tack strips...
