yes you loosen 6 8-32 screws and insert shims and then re-tighten. bruce make the shim so that you do not have to completely remove the screws. mine last about 1 year of racing before they start to get loose. but since, I have been helicoiling some of the parts so that I don't have to worry about it anymore. i helicoil the front end, body posts, and antenna mounts right of the bat.
