no idea if it's sufficient
It's incomplete, so you have to fill in the blanks. Obviously the production ones were not CNCed from billet, so just drawing it still leaves work to do before you can make it. This sketch hits the functional dimensions identified on the Cane Creek drawing, but one would need to inspect the mating parts to see what changes could be made in the name of manufacturability without breaking the function. For example, if the M6 threads are tapped through, they notch the 8mm bosses, which seems like a bad idea.
