Angier,

 

>>be sure to properly shim on either side of the drag link.

 

Explain the shimming part. 

 

Looks like the existing drag link, being somewhat smaller in width than the tabs, was made to 'float' there and be self centering to allow for slight misalignment during construction by various builders. 

 

If it gets shimmed too much then it would be in conflict with the sides of the drag link and/or tabs?  Thus friction and wear?
