3. Unscrew and remove the quantity-4 rail kit rear-mounting bracket screws to adjust the rack post-to-

post distance for the left rail subassembly.

4. Relocate the left rail mounting bracket to approximately match the rack post-to-post distance

recorded in Step 1, above.

This bracket has one inch of available adjustment after the screws are secured. After torquing the

quantity-4 screws removed in Step 3, verify that the bracket can be adjusted to the exact rack post-

to-post distance determined in Step 1. Torque to 1.36 N-m (12 lbf-in)

5. Repeat Step 1 through Step 4 for the right outer rail subassembly.
