would i have to put washers on all the 4 bolts holding the control arm..or just the upper 2..or just the bottom 2?

im assuming that they would have to go on all of them to properly alter the position of the control arm..just wanan double check before i go thru with it.

it seems pretty straight forward..good thing the bolts werent torqued too hard..but just in case im missing something..anybody have any tips?
