Hey I'm a member of the Michigan State University Formula Racing Team and I have a question to ask about a spline I have. The salisbury is out of a BMW and is the medium size (small, medium, and large were offered I'm told). It is a 27-tooth spline with a max shaft diameter of about 1.17", and a minimum shaft diameter of approx. 1.06", with a spline length of about 1.25". Any information or part numbers would be appreciated, although i know the limited information may prove to be a tall order. Thanks!
