Have not looked at rear..assumed it is a standard ford 9".... have window sticker laying about somewhere, so i may off a point or two on teh gearing (2.28?) but either way it, umm, sucks. Posi would be cool too, but as i no longer drive this in the snow it prolly don't matter. If i upgrade the motor to the point i need a posi, i'll go there.

Didn't know ford made anything 'bigger' than a 9" (unless it was for dem BIG trux)

any notes on telling the diff? i have the car up in the air for wheel well repairs...easy enough to look at this point!
