I am doing a diff for my truck .

I have a spare diff head that I think is from a '55. The one in my truck is from a '54. These should be the same item.

I am looking for the carrier bearings . KC11445Y. I have looked at several sites , but they are offering a taper roller replacement. I cannot see how an item engineered for barrel roller will accept a taper roller and not subject the taper bearing to undue point loading.

Can someone please help me locate the correct barrel roller bearing .
