maddog34 ditto for you too.
The two most standard sizes of barrel adjusters are the larger M5 (same as for mounting your water bottle cages and rack/fender mount points) and M4. Try a water bottle cage mount bolt and if that's too big, there is a 99% chance it is M4. Let me know, I have both sizes.
