Transmission Gurus, please help me identify this piece

I have put most of my Torqueflite back together after a set of new gaskets and seals and replacing a cracked output shaft support. I found this guy sitting on my workbench, glaring at me for leaving him out of the mix. What assembly does this belong to? It's the first time I have ever seen it so any help would be awesome.

Cheers,
Joe

Goes into the planetry gears as a spacer or into the rear drum as a spacer.

goes on the end of the output shaft,as it mates into the rear drum,which holds the input shaft. it is the bushing between the two shafts.

Thanks guys, I got it put back where it belongs and I'm on the home stretch to completion.
