Re: Super major rear dif ratio
The number you quote is not in the Fordson parts book. The part numbers given for the complete pinion and ring gear are:
E1ADDN 4209 1952 to 1960.
E1ADDN 4209A 1960 to end of production. 3.5 to 1, High Ratio.
E1ADDN 4209B 1960 to end of production. 4.375 to 1, Low ratio
However, in my book, penciled in by the storeman "8-35" is next to the low ratio, so I would be 95% certain that yours is a low ratio. I also have a High speed dif and pinion in stock. This is not marked with a part number just the date in 1962 plus the numbers "8-10".
The E1ADDN4210 number refers to the crown wheel itself which were never sold as a single item but always with the pinion as a matched pair.
