Hi y'all, Picked up a 04/05 600 shock (ebay) to put in my 03 750. Shock looks great but there are some small rocks in the sleeve part at the botton of the shock. They are obviously too big to get out of the small gap (even with squeezing the sleeve but it doesn't really open up). I suppose it could be internal parts but sure looks like small stones. Any thoughts? Thanks!
