Here is the NAPA number for my T/O bearing....N1181
This is basically a 1967 T/O bearing that is meant to be pressed onto a carrier of sorts. The ZF version(?DeTomaso??) is a cast iron sleeve, with two ears on it that are held to the T/O fork with a special spring clip. This T/O bearing is pressed onto this carrier. I don't think you will find a "stock" replacement type that will work if you don't have the proper carrier.
Please advise if you need more info, and perhaps I can take a picture as mine is out of the car at the moment.
