The number you posted are for an 8n or 2n. The numbers weren't that high for the NAA 1954.The 2n should work but I don't think the 8n will.
Don't forget that Harry parted ways with Henry in '46 and the T0 was styled after the 2n with some improvements. So I would think the 9n and 2n axle should work. How did you go from a ford 2000 to an 8n/9n???
