A body Steering Boxes

Chrysler had the standard manual steering boxes and also offered a close ratio one. I have that in my 69', in the photo. not sure of anything else except the pitman arm is different from 68' and up, from a 67'. 67' is on its own with that. As stated, steering columns are different from power steering (short shaft) and manual steering (long shaft).
The '67 Idler arm is unique, but, the pitman is the same as all '67-72 A-bodies except for the factory big block cars.
