Scott,
Your request sent me to my Fox parts drawer. I thought that I hada new 15X head in the package. I did find a used one loose in my collection. It appears to have good threads. The finish is not shiny but the surfaces are clean. It looks as if the gasket is new. Yhe head is used but in pretty good shape. If Fox did not have one send me a P.M. with your address; and you can have it for the cost of postage. I am in Alaska so the mailing distance is zone 8. I will find my tap and check the threads before I send it. I will also check the local HS for a new one .He has a box full of odd Fox parts.
