You'll need the flange, too. There are two out there. One with concentric OD and ID with one edge with a flat cut. The other one has a sort of egg shaped OD, and no flat. That's the more correct one.

As for clones, there's a wide difference between Yenko clones out there. Everything from 350's with Yenko stripes, to very accurate replicas. I would not use a clone as a model for building your car.

As for your 10 10 car, Jack Douglass Chevy in Chicago made their own "semi-authorized" Yenkos, and used colors outside the 6 Don used. I don't know if they made any black ones, but maybe Steve Bimbi, from Nickey (stefano) could shed some light. He's quite knowledgeable, and very willing to help.
