Manual Steering Pitman Arm Question

The steering gear changed in '73. Prior to that, they all used the same Pitman arm whether it was power or manual. If you want to use the steering box from a '70 Duster, you can. You will need the steering box, Pitman arm, center link, and idler arm. If you have access to the Duster, that may be the way to go. The '73 up manual Pitman arms are getting hard to find and pricey.
