Hotchkis 22390R Sway Bars, Rear, Blade Style, 63-72 C-10 - Manual (Page 6)

Once you have the 2 holes on each frame rail, we can install the sway bar, bushings
and brackets. First, grease the inside surface of the D-shaped bushing. Install
the bushings onto the sway bar ends. Next, install the bushing brackets onto the
bushings.
Position the sway bar onto the truck as shown. The sway bar lever arms point
towards the rear . Use the hardware from bag #17118-1 to mount the bushing bracket
to the frame. The longer bolts (1.25”) are for the front hole and the shorter bolts
(1”) mount the rear holes. Center the bracket so that the holes are in the middle
of the bracket slots. Fully tighten the bolts.
