The rims for the 46 would be the same for the AD Series. 6 lug 5 1/2 spacing. I am not familiar enough with model years prior to 41. Whether you have 15” or 16” rims the following specifications should apply:
Tire size and ply rating
6.0-16-6
Rim size
16 x 4-1/2
Offset
9/16
Attachment
7/16-20 bolts, 5-1/2 bolt circle
I assume the offset and back spacing are the same seeing that hubs interchange.
