tc ts bearing pn

I did a 231 sye tailshaft conversion for a selectrac on my '98 about five years ago. I think I need to replace the tailshaft bearing, the double-row one that came with the currie/sixstates kit.

Is that tailshaft cone a common one, what I'm really asking is does anyone have the pn for a Timkin unit to fit it?

Thanks, Mike M.
