Suspension parts list. What's missing?

The project car ('73 Duster 340/auto car w/ P/S) vs the parts car ('73 Duster /6 3spd car with manual steering). All being the same, the steering boxes should drop in with little change. Am I right?

The power steering column is shorter than the manual one and has a different spline count. If you swap the box from the parts car, swap the column as well or use the power to manual coupler from Mancini's. FWIW the '73 up manual steering pitman arm is getting hard to find and quite pricey. :angry7:
