Have a 57 with manual steering and am amassing the parts to change to power. I've been told that pitman arm has to change as well as some of the lower steering components also although no one seems to be sure. I have aquired the assembly ( pitman arm down) and for the life of me can't see the difference between my manual arm and my aquired power steering arm. Can someone steer me right? (no pun intended!) Thanks - John

 

Here's a breakdown , (no pun intended)
Group # , description , the same?
6.103 Plain (steering) arm , no
6.230 inner tie rod end ,no
6.233 outer tie rod end , yes
6.859 pitman arm , no
6.895 idler arm , yes
