69 Valiant manual steering to PWR Steering question

Gents,
We are currently pulling the engine for a swap, so We decided to upgrade to PWR steering. we pulled a steering box from a 71 Dart. The steering unit is larger than the Manual unit. From the center of gear to Roll pin, its about 3" larger.
My question is, Does the steering column Collapse at all to accommodate the larger unit? Or do you have to have a different steering Shaft / or column for the Power unit ??

thanks
Earl
