I have a 2000 small block. Mine has 2 plates (spacers) under the left hand cover (as your sitting on the bike) and 1 under the right hand side with the rear brake caliper bracket acting as one....Hope this helps
Ray, I believe yours is a 2004 as is mine. My bike has 2 on each side, one on top of the other, under the chrome covers. I'm not sure how you could tighten up the adjuster blocks without them. Also I would think you would seriously damage the chrome covers without them. Forgive me if we're talking about two different things here, and if so, disregard everything I just said :?
