INSTALLING THE DRUM GUARDS
1 Secure the shorter left and right drum guards using one 3/8 x 1.25-inch button-
head bolt each.
Note: These drum guards are shorter than the left and right drum guards for the
stationary dyno and must be mounted on the 4WD dyno.
2 Secure the rear drum guard using the center 3/8 x 1.25-inch button-head bolt.
