supplied screws (109, 110), flat washers (111), lock 
washers (113), nuts (117), adhesive (115), and 
mounting plates (118, 119).

NOTE:

 Installation of the mounting plates (118, 119) will 

require that one of the plates be installed over a bolt 
head welded to the upper carriage. One mounting plate 
(119) has a counter bore to clear this bolt head, so make 
sure that mounting plate (119) is located correctly 
before starting the installation.

NOTE:

 When installing the mounting plates, hand 

tightening the bolts is sufficient for this portion of the 
installation. Do not overtighten. Final torques will be 
applied in step 16.
