Sounds like a late 70 Nova build or possibly a 1971 Nova 3:31 Open.
W would stand for Warren,Mi. plant.
I had heard these coulda be used a lil longer then 70,as well as used on the Nova too but not sure.
Do you notice the letter C anywhere in front of the BM stamping?
Can you measure the axle tube flange to flange?..is it 54-1/4 or 55-1/4?
Is the measurement between the centerline of the spring seats 42-7/16 or 45-3/8?
