Install Mounting Hardware

Using M6x60 bolts, attach a pair of pivot-bracket and latch-sting-bb to the rear BlueBoat crossbar. The two center holes in the crossbar should remain open. The pivot-bracket parts go on each side of the center holes as shown. Note the orientation, and remember about not tightening the nuts until all the parts are attached loosely.

Using M6x45 bolts, attach a pair of pivot-bracket to the port side of the crossbar. You will need M6 anti-corrosion bushings on the side with the exposed crossbar.

Install two more pairs of pivot-bracket on the front crossbar, directly forward from the pairs on the rear crossbar. Use M6x45 bolts on all four brackets, and don't forget the M6 anti-corrosion bushings.

Using (2) M5x25 bolts, install the smaller piece of latch-sting-mech to sting-latch-bb. Install latch-sting-mech so the adjustment screw is accessible (pointed down).

Using (4) quick-release-0.25, install the Sting and GNSS Crossbar in the brackets in transport position. Go around the assembly and tighten the bolts as you pinch the pivot-bracket pairs against the Sting and GNSS Crossbar. Make sure you can remove and re-install the quick-release-0.25 pins easily. If not, loosen the nuts and re-adjust until you can.
