STEP 5 - INSTALL DROP DOWN MECHANISMS TO CROSS MEMBERS
Installation will be easier if you can get more access between the rear cross

cross member to the mounting channels. Remove and retain hardware for re-
assembly in Step 6.
Ensure that both sliding mechanisms are on the same cross member
and both xed mechanisms are on the same cross member.
