Clutch release mechanism.

Evening all. Wonder if anyone can help. In an ill-advised attempt to adjust my clutch I have managed to snap the end off the adjuster screw on the release mechanism. The screw I am refering to is the one on the adjuster which is screwed in / out after loosening the locking nut that surrounds it. I have managed to get the screw out but was wondering where I would get a replacement. Will my dealer be able to supply just the screw and nut or will I need to buy the complete release mechanism. Sorry if this doesn't make sense but I am not the most mechanical minded person there is.

Thanks for any help,

Paul.
