<VV> Part question...Bearing application

[paulsgt at aol.com]

Greetings!
I purchased a box of Corvair parts the other day which contained two Delco Hyatt roller bearings.  The numbers stamped on the side of the box read:  1 # AD11154Z17  - next line - 7451321
 
Can anyone tell me what is the application for these? Are these FC rear wheel bearings?  I am guessing they could be for a Tempest too(?)
 
Thank you for your help!
