Here is a shim that was broke in the exchange valve on shock. Don't know how it even happened or what could have caused it to break. These two pieces is all that was in it. I couldn't find the third piece or know were it could have gone. This shim sits on top the the wave washer or wave shim. Where can I get these shims at? The sizes are Wave shim= 21.4 x 0.11 x 18.4 Broken shim= 21.4 x 0.80 x 17.5 Would SDI or Technical Touch have these?
