you’re correct the front pinion mount takes care of the rotational torque and the top piece connecting the two mounting tubes there is no clearance problem in the 289 chassis
As I remember the 9” did have tight clearance on the top because I use the cut down 9” housing which has a greater OD than the C3. Do not remember the width of the 9” it was wider and a ***** to get it in the 289 chassis. I made the notches on the inside of the main rail tubes little longer and deeper. Remember I did this almost 40 years ago!

u joint. Do not remember which stub shaft I used.
