It was the only part they had with the o-rings so I took it. I just thought that it was unusual that the inner section fit into the stock ford housing, so I changed out that section instead of changing the 3rd 0-ring. Also unbeleivable that their part was $12 vs $64.That part # must be a 94-97 drain valve if it's held on by only 2 screws.
I'll bet that International has the later 99-03 drain valve.
Here's some photos of a 94-97 drain valve.
