1972 Twister /6, thanksWhat 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.
Well both, but b-body trans. I have an extra case with the smaller bearing and I have the diagrams for the shifter mount. It all will be going back into a 69 notchbackNext question, which 4-speed overdrive or standard 1:1
1972 Twister /6, thanks
Almost certain the /6 I took out of my 70 only had the tiny 3 speed bolt pattern but the 72 is hard to see being on blocks but thought maybe since it had the full synchronized trans it might be the one. But you know Chrysler..Four speed and slant, My opinion is it takes a specific slant bell for the 4 speed. but I have been wrong before (once).LOL...,there were 2 #s of such, which I forget. Sems like they were early bells. Rare and $ if you find one.
Okay, slant 6 may be different, I'm not as familiar with those.1972 Twister /6, thanks
