I didnt save mine. It was pretty easy to make. I just cut a circle and then bored the hold for the nosering. Then I just used my belt sander to whittle away at the top and bottom until I had a perfect fit. Once you get the fit you want then you can trim away the excess on the sides so that it doesnt show in the cheeks. Once I had it built I painted mine black, you cant even see it in there.
It has held up perfectly to the 1.60DZ's lope really well so far..

There are some pictures of the general shape at the beginning of this thread.
