I'm confused. It says fine spline for a 3B. So it has the wrong input shaft for that motor? I was of the understanding that all B motors had
the same input shaft so they were interchangeable. As I thought the B, 3B and even 13BT all shared the same input shaft?
Correct me if I'm wrong since I just don't know
Also, why sell a transmission stacked with transfer if transfer is not for sale. Seems a bit fishy, as maybe the transmission for
sale isn't the one in the pic.
My understanding is the same that B engines use the same input shaft. It’s also my understanding that it’s significantly longer than an F input shaft (1.5” longer).
