wow! Where did you get the top one? That doesn’t look right at all? I have seen and replaced several valve stems, (not lately), but they all looked like the bottom one, I think your missing something? But they do change on the fly so ya never really know, I would call them again, I have called Fx USA at least a dozen times, they have not been difficult to get ahold of at all? I always call in the AM, good luck.
