8 3/4 gears

[ir3333]

just pulled a set of 4.10's out of a 69 Dart 8 3/4 rear
the casting number is 182657?
...anybody know what case a 657 is or the size of the pinion?

The 657 center should be the same as a 741 with a 1 3/8 pinion. That center section came in the older rears (57 to 64) with the tapered axle shafts. It was last produced in 64, it will, however, fit into any 8 3/4 rear.

1820657 is the casting number for 1957-1964 with the old style axles. The housing would be the same as 2070741 in 1964 to1972.

Yep, I got one out of a 58 Dodge 1/2 ton. It has a 3.58 ring and pinion.
