National Grease Seals

Does anyone know where I can buy National #442270 grease seals? I have a 1970 Overlander and am having difficulty replacing the grease seals.

NAPA Cross Reference

I found your no. crossed to NAPA 22550 National Oil Seal 2.25" X 3.375' X .375" however they also have a cross to 13612 NAPA Oil Seal with smaller dimensions.

Not employed by NAPA.
