A body Steering Boxes

There again, I'm talking about power boxes, not manual boxes! For 16:1 manual boxes, 72bluNblu is correct....A-body only from '66-9. They were all bearing type boxes too. Chrysler came out with a 20:1 gear set later on as an optional replacement for 16:1 or 24:1 ratios.
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).
