Duster bell housing
What year? If it's '69ish or later (car), it should have the dual-pattern bellhousing, used with both transmissions. Earlier bells were trans specific.
Slide under the car and take a look. Even with a trans in place you should be able to see the other pattern showing on the bellhousing.
My only concern is that the retainer hole matches the diameter of your particular four speed, they varied by year and original application.
Edit: I see now you said Duster in the thread title- so it should be the dual-pattern bell.
