to the rear suspension link. Connect the free end of the 12-foot sling to a 3-foot (4-loop) sling
with a 5 1/2-inch two-point link.
2. Attach a 3-foot (4-loop) sling to each center suspension link with a large clevis. Place both 3-foot
slings in the bell portion of a large clevis. Pass a 16-foot (2-loop) sling through one spool of a
three-point link. Place both end loops of the 16-foot sling in the bolt of the large clevis.
3. Place the end loop of a 12-foot (4-loop) sling in the bell portion of a large clevis. Place the bolt
of the clevis in the bell of a second large clevis. Bolt the second clevis to the front suspension
link. Bolt the free end of the 12-foot sling to the three-point link on thecenter suspension sling.
Bolt a 3-foot (4-loop) sling to the remaining spool of the three-point link.
