I really appreciate the help.

So the correct spec is 72.56 to 74.1. Funny, but the "certified" parts associate at the local BMW center and his Manager both swore and told me that it was 74.1 to 72.56., and that I was wrong the other way around...

Since you are going from a smaller hub to a larger one, the formula should list the smaller diameter first, the larger second, right??? Hub -> Wheel...

Oh well...
