i have alot of small detail questions. they say the devils in the details. when installing shock bolts to my rearend do i use a washer/lockwasher combo on the big side? or is the stock nut a locking nut? not the shock side.

Should be flat washer/lock washer/then nut like shown on the attachment. Look down at the bottom of the page.
