Can you identify this "clutch Release Bearing"?

A few pictures would definitely help. See if this link helps on the posting of them.

The "1697" bearing is a standard throw out bearing used in very early Chevrolet's and most GM's up to the 70's and well beyond. I have gone through a few of those! They can still be purchased as a NB1697C.

Usually it is the stock throw out bearing used when adapting the T90 transmission. Typically there is a modified front bearing retainer that the stock throw out bearing rides on. Some pictures of the adapter kit and the front transmission bearing retainer will help. gmwillys and TJones have a lot of experience adapting different engines to the T90. They will jump in here with some help.
