440 Swap Steering and Front Suspension Rebuild

Manual steering boxes for the A/B/E bodies all use the same sector size. Only the power steering boxes changed to a larger sector shaft in ‘73, the manual boxes were identical for sector size. The center link changed in ‘73, so did the pitman and idler. The orientation of the ball joint was changed, the later ones point down. So, if you want to run a 67-72 center link, just run a 67-72 pitman arm and a 68-72 idler (unless you have a ‘67 K).

The factory manual steering box is probably the best you’ll do for clearance and size. I have a flaming river box in my Duster and it’s mostly bigger anywhere header clearance would be a factor. Not a lot but it wouldn’t help you.
