Top Fitment Question 72 K5

[72K5NTX]

Where should the top fit on the bed rail of a 72 K5 with a double wall top? Just finished the resto on mine (top not truck) and need either advice or a pic or something. On the driver side, the inside of the top is 3/4 of an inch away from the lip of the bed rail and the back hold down bracket also has a big gap. Passenger side is also out in the back but not so much. Of course the hatch has never closed properly (or been on) since I bought the Blazer. Also how much should the back corners of the top hang over the bed corners? Any help or advice would be appreciated. By the way all body mounts are new and shim ed with top on. I will try to add pics
