Source for replacement Janome serger parts?

[stretchmark]

SOmehow someway a part was lost to my serger right after I got it. I think it is called the "spreader" and is the part that allows you to use only 3 threads 'cause it blocks off the 4th thread.
Where can I just buy this part?
I guess I can ask my local sewing machine guy.

Your sewing shop should be able to help (or check www.janome.com -- maybe you can order directly from the manufacturer).
