Exactly right, JW. The hubs are different. I may be readu=ing the parts book incorrectly, but in the 12.000 section, it shows this:

Axle
340110 is for 1800
323143 is for 1801,1803, 1804,1806,1807
338693 is for 1808,1801A,1803A ambulance

Hub/Drum Assembles
347048 is for 1800
341982 is for 1801
351423 is for 1803 (my car, same as Jim Wagnon's), 1806
333931 is for 1804, 1807, 1808
333200 is for 1801A,1803A

So the axle-end taper is the same for 1801-3-4-6-7
But there are 3 different hubs/drum assemblies for that axle.

I wonder if the 1940 drum (that's all that was painted on the drum "Pack 1940") could have come from an 1801, 1804, or 1806? Since the flackmaster was saving it for Jim 1803, I assumed it was from a 160 or 1803. I'll check with him to see if he knows.

In the melon time:
My original hub inner ID is 1-5/8" and tapers down to 1-3/8" at the outer end.
The new hub inner ID is 1-1/2" and tapers down to 1-1/4" at the outer end.

The stock used for the hub is the same. The thickness in the outer wall is different by 1/8" between the two hubs. So it looks like, if it's possible to machine the hole on the new hub larger so it matches my original, that would be my next step, esp since the studs are already welded. At least I have the original hub for duplicating.
