Looks to be a 322 or a 355 ratio-not sure.Open differential-not posi - but it is a 9" rear.

The most narrow rear that Ford made.Will bolt in and fit under the Baby Birds without any hacking.

Believe its 50 1/4 wide from inside of the backing plates.

Its that round smooth looking rear that the rod builders prefer.

$200.00 here in Balto.Md. Prefer pickup as shipping a compleat rear is a tough chore.
