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.

Get a NOS seal, remove the inner seal and replace it with a new modern seal and also use a redi-sleeve. Custom made seal holders may cost you big $$. This set up is a lot cheaper. Redi-sleeves are a bit costly though.

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).

I have some steel on its way. I'll be machining two seal adapters. I've already taken measurements and drawn up the plans. These will be sweet! Having a small lathe and mill is a real life saver! I'll post pictures of the adapters when I'm done. Some of you may be interested.
