Turns out I bought an Eaton H052 rear axle housing cover gasket from BTB:

Felpro RDS 5088 Rear axle housing set
Chevrolet Truck
1937-1972
Replaces 3665606

I have my '72 pickup's Eaton H052 rear cover off, so I lined up the gasket. Fits perfect. All precut holes line up. And I thought the gasket was paper, but it is ~1/16" and both thick and rubbery, like it is rubber impregnated paper. Definitely not cork. Not just smooth rubber. It has a texture. I'm not sure what it's made of, frankly.

D.PASS, Some H052s can have the ring gear deflection bolt in the side of the third member housing. I have a '71 K20 burb with 12"x2" brakes and a '72 K20 pickup with 11"x2.5" brakes and they both have third members with the side bolt adjustment. I'm guessing the deflection bolt came on later model H052s. I'm still learning about Eatons.
