Dimensions of rear hubs

[jnunez1955]

Hello, i was wondering if anyone out there can help me get these dimensions.
Im trying to figure out which one i should use, since i know they all have different offsets and dimensions.


I need to know the dimensions of the rear hubs from the following 3
1930 Model A rear hubs
1940 rear hubs (that mount outside the drum)
1946 rear hubs (that mount inside the drum)


heres a picture of what things i need from it

Early Hub (non-AR):
A) 0.275
B) 7.250
C) 5.825
D) 3.250
E) 2.300



Later Hub:
A) 0.290
B) 7.250
C) 5.875
D) 3.280
E) 2.300

Measurements taken off of used cores and not factory prints, so allow for wear variations.

for the earlier hub, do you mean the Model A or the one that mounts outside the drum?

I think what Brent is referring to is the fact that there is two distinct rear hubs for the Model A, one has a groove part way down your "D" dimension, and the other one has a raised lip or ring around it. I think the one with the groove is the earlier of the two.
