The "old" style hub has square, notched cutouts in the shift hub. The
newer ones are more raduised. The Bentley mentions the difference, but I
think it was the same part #. There is a picture of the old style on my
web site at:

The difference between the 2 styles is obvious, so you should be able to
tell the difference. I wish I had the digital camera back when I replace
my 1987's hub with the new style in 1995.

Good luck!
