I have just replaced the upper control arm bushings, and I forgot how the washers went on, since I took them apart bout 2 months ago. Anyway, I have the two thin washers...one against the head of the bolt, and the other the nut. Then I have thick washers, and thicker washers (about twice the size as the thick). The FSM shows these washers as being the same size. Is this true, or does the thicker one have to go on toawrds the front, or back.
