46RH Need help finding new pump

I’m in the process of rebuilding a 46RH and the stator shaft has been scored quite deep from a convertor someone had on it.
I’ve been trying and trying to find a replacement for it. Does anyone know if one off a 47rh Cummins will work on a 46RH beings that it’s a non lockup.
I found one on eBay that came off a 94 46RH cummins and the part numbers are the same... so.....

Not sure what you are looking at though as far as scoring from a torque converter. Can you post a pic? Generally pumps from these trans parts suppliers do not come with the reaction shaft, that's a separate part.

In 94 the "Cummins" trans was a 47RH and it was a lockup. Whoever is selling that part doesn't know what they have, it's either not from a 94, not from a "Cummins" truck, or it is a lockup shaft.

I’ll get some pics posted of the scoring on the star or shaft as soon as I get home. Isn’t the stator all one piece? Meaning the shaft isn’t pressed in correct?
I verified the part number on on both stators again and their both 4428444.
I took my chances and ordered the Stator/Pump.
