6. WINDSHIELD (continued)
6.3 To close, grasp the windshield bottom edge and lift slightly while pushing
closed. Fully close latches. Align sides of windshield with side frames and
tighten hinges. HINGES ARE PLASTIC COMPONENTS. DO NOT OVER
TIGHTEN. TORQUE TO 7 FT./LBS. MAX.
7. ROOF
7.1 With assistance, install roof as shown using 5/16 x 3/4” long button head
screws, plastic washers, steel washers, and locknuts in all holes except the
middle ones on the left and right side (these two bolts do not require lock
nuts). (see fig. 7.1). (Also note: front left, and front right corners take 1”
long bolts)
8. REAR WINDOW (hard side only)
8.1 Install two (2) ball studs to the inner curved surface of the window (Note:
the Philips head portion of the screw is to be on the outside of the window.)
The base of the ball stud goes against the inner surface of the window, with
the boss sitting inside the window hole. Bolt these components together,
making sure that the ball portion of the ball stud is facing the outside edge of
the window as shown in fig. 8.1.1 (so that the gas shocks will be as close to
the edge of the window as possible.)
