Does anyone know the length of the rear end for a 1967 mustang ?

I have found a 9" and it measures 51.5 inches form inner hub to hub.
The perches are 43"

Will this workout with some mods or not ?
thanks in advance

I don't know. *All* rear ends I've seen are measured flange to flange.
You might want to go back and re-measure.

67-70 Mustang 59 1/4 inches

Dave W. personally measured:

I just measured the 9" housing from a '67 Mustang big block car.

The perches are 43", on center.

The housing is 54 5/16" from the outside of the bearing flange to the
other. This is the surface where the brake backing plate sits.

I'm not sure exactly what you mean by inner hub. Generally, these
things are measure either between brake backing plate flanges as I
did this morning, or between the axle flanges.
