Lil help....bearing identification

[dustoff440]

I have no idea where these bearings would go, the pn's are too faded to read??????????

Are they tapered? Could be a pinion bearing.

Most likely a rear axle bearing for some sort of "C clip" axle, who knows what, as Ma, Ferd, and GM all used 'em. Depending on where you got 'em, they might not even be automotive. Those ain't tapered, those are needle roller bearings
