I can't really help you directly but this link may be of help:

I think you can get the parts schematics and compare..

Also, I wanted to thank you for posting this. I just bought a 2003 8.1/Allison 1000/NP263XHD with 185k miles. I didn't know about the pump rub issue and researched it. I went out to my truck and found a pinhole and wet transfer case...
looks like another weekend day soon to be occupied! But, that's better than a grenaded case and being left on the side of the road.

Best of luck!
