it was packaged together with the plug - wrapped up in plastic and taped to the fork.
it was less than 1 mm thick, so i doubt it was the shim you speak of - silver aluminum, textured coating - looked like something to help the expansion plug "bite" - but I'll be damned if I could figure out how to use it with my fork ....
