    Bushings are pivots, those are what the bolt goes through, sometimes there's a larger pin or axle that is used. The things on the sides that are sometimes narrow or wide are spacers.

    You likely do not need bushings, new (even old shocks usually) come with bushings. The spacers on the other hand, you have two general paths to try. One is to contact the bike manufacturer, see if they can give you the correct size. Measure the spacers with a caliper or what you need. The second way is to contact the shock manufacturer. In either case, if you get a new shock, you have to make sure it's the correct length and stroke, then you have to make sure you get the right size spacers.
