What Zenith carburetor was used on a 1943 B?

I ordered parts for my AC B, which was built between 1941 and 1943, and received incorrect electrical parts, so I am also afraid that they ordered the incorrect carburetor kit also. My IT manual states it will either be a 61AJ7 or a 161J7, is this correct and if so, how can I tell them apart?

Also, I noticed on my I600 (or 615, not 100% sure) the insulator, that the condenser and points attach to, is on the outside of the distributor and on the B, it is on the inside of the distributor, which is correct? I would have thought it would have been on the outside, but am not sure now.

I don't think it matters much what was used in 1943, what matters might be what carb is on your tractor now? In 70 years, lots of things could have been changed. A basic kit with just gaskets and such will probably work OK.
