Hy davesmith, I'm not positive about these numbers as my crossover book for bearings doesn't include a lot of the NDH Barrel bearing numbers. I think the assembly number for the tapered roller bearing replacement is KA-11035-Z, the components of that bearing are Bower p/ns 15579A and 15522A, you could have your bearing guys look up those bearings for dimensions to verify that they are indeed the correct size for your application, hope that helps.
