We aren't sure why this hose was reproduced as shown. However it will work with the stock PCV valve and elbow if you cut off the non-flared end.
This hose uncut will fit like a glove on 1966-67 Thunderbird, and full sized Ford and Mercury with the 390 engine. The original hose would have had a part number of C6AZ-6A664-B. One of our T-Bird customers is positive that it fits. Irv has a concours 1967 Thunderbird with 390. He is very happy with the cut fit of this hose on his 67 Thunderbird.
