Rear drum part number for a 72 Duster?

Wow, I had no idea they were that scarce and that the parts stores don't have the right drums. I don't care if they look stock at all, they just have to work correctly. I have the rear drums, it's just that they appear to need alot of turning to get them smoothed out so I figured it would be better to buy new ones.

Whitepunkonitro, who has the ones that fit but don't look stock? If all else fails I'll just have mine turned and see how they look and feel.
