I have a used but like new clutch. It is a 10.5" 23 spline. Borg & Beck stamp on housing along with the word Model. But no other identifying information. It has 12 springs, 3 rollers and is gold plated/painted. How do you know any specs? Is this real B&B, or some ones remake/rebuild? Seems like some other manufactures use the terminology B&B style, and others state B&B like Hayes? Is this a case were it is made under license? Thanks,
