3 speed tranny question

If original to a floor shift Duster, it will be a side loading A230.

I bet the '66 has a top loader.

If anyone has done this swap before & retained the column shift, I have not heard about it before?

66 Dart slant 6 bought it with out a tranny so don't know what it had originally. I am parting a 70 duster with floor shift slant 6 I was hoping I could use the tranny and retain column shift. If not I will be looking for a top loader tranny.
