Shock installation is the reverse of removal. Begin by installing the shock with rear eyelet hardware 
into the yoke. It is important to observe the orientation of the adjuster cap and eyelet reducer as the 
two parts are keyed and will only assemble if aligned properly:

 

Similarly, the shock pin is keyed into an oval recess in the lower jaw of the shock yoke. Ensure 
alignment as the pin is inserted:
