Anybody added power steering to a 67 4wd

[gregbr]

I would like to add power steering to my 67 4wd....it's factory 4wd on the original 67 frame, with a weird looking manual box. The frame is straight on the front, no dimples or raised parts for mounting the box. I noticed my 76 4wd and my 70 2wd use the same box, can this box be installed on the 67 using spacers of some sort along with the pitman arm and linkage to bolt to the 67 arm on the axle?? Will new holes have to be drilled? What is best here?? I'm installing a later tilt column and intermediate shaft now. Thanks
