The current drum is machined -- it is not legal (and hasn't been - it was simply not enforced.)
This also became a point of contention from the other clutch manufacturers qho wanted their clutches made legal, or the ability to offer machined drums.
The nice thing is, the company, Premier, is taking care of their customers through Target Distributing.
VERY NICE (and professional) move on their part.
