I bought a Primo Casket bmx stem and a no-name shim. The shim is longer than the stem. The main reason for buying this stem was because I want a short reach. But now that I bought it (and bars to go with it) I'd really like for it to work out.

I've properly tightened everything a couple times, removing and adding some spacers to see if anything would work. No luck. Are there shims for bmx stems out there?
