Actually they were the OEM manufacture in the day not just a style. This is the 3 finger and I understand the difference versus diaphragm style.

I have seen original B&B, and B&B with model numbers and B&B with reman. sticker on them. This one does have the same stamped B&B and "Model" stamped on the housing, but no patent info like originals, or Model number like others I have seen.

I was hoping for more specific info on the clutch. I would have thought it would have a manufacture name and or model # stamp. Is Hayes Licensed to use B&B name?

The Scalloped 70-71 11" came in 3 versions, 383, 440, hemi. Service manual tells the difference. The 10.5 was for the 340. Was wondering if there was some standardization on clutch to know the design spec and intent for this clutch. Who used gold paint/coating on disc hub and yellow treatment on housing?
