Looking for a 14 inch tail housing for a 1969 mustang. The casting numbers that will work are c7or-7a040-a or c6or-7a040-a. Ford made the two housing either way 28 spline or 31 spline. Maybe trade you for a 31 spline main shaft(long) and a 17 inch tail housing(long) number c9or-7a040-a. Thanks for looking
