Manual steering to power

Did my 70 Duster a couple years ago, your on the right track. Got a ps shaft from someone here, was easy to install in the 4 spd on the floor column. Exhaust manifold had to come off to get the box in. I put in a firm feel stage 2 box, a stage 3 wouldn't be bad either. Also I installed the bearing at the bottom of the column, saw it in here somewhere and it does feel better.
