Sorry FJ, misread your post, I thought you were talking about the tensioner BOLT.

Don't know what you're looking at on fleabay, but I have a few used tensioners lying about, presumably from '65-'67 engines, and they're all the same. I don't know what would have changed in the primary in '71 to require a different tensioner.
