I know this is an old post, I had to make a new such piece myself when I bought my 267-373 years ago. Made it from a piece of hard plastic, the old way with saw and file. Then I ordered one from my local DA dealer, price was under 10 US$. Lesson learned, check availability first. By the way, even when your machine may not be supported anymore. This part is the same on the newer machines , 267, 268 and 269. Maybe on more models too.
