Differential pinion seal part numbers...NAPA?
Other than NOS...Anybody have some numbers? National,CR,napa,kragen?? 

I think you can can get only NOS try Vintage Power Wagons or Midwest Military.
BUT if you want to end leaking and use modern seals contact Charles Talbert at Mseries Rebuild and buy his adapter plate that allows you to install a modern double lip seal and you will be very happy. He sells the complete set up with the seal and a sleeve for your pinion.
Mine has not leaked a drop since the day I installed it.

I haven't tackled the axle pinions yet but I do see that Cabel's parts conversion list shows the Pinion seal 741182 as Napa 49614, CR 12305A.
Pinion bearing G741-703109 as Timken NA44143 (2) & 44363D (1).
