James, that's an excellent point, and you might be right. I was under the impression that the SVO & turbo T-Bird had a larger diameter pilot, like the V8's, rather than the usual 4 cyl. size. If you're right, then the input shaft will require a different pilot. If I'm right, it's straight across. Your link may have had the answer, but I'm too tired to go read it.
Take care,
