Anybody added power steering to a 67 4wd

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

flat frame .

Well you have three options my 67 had the same set up except the area around the box was trashed so i welded a newer type frame horn on . As far as what you can do is use a newer style box and shim it out with spacers or get angry and use a big tourch and heat the frame and beat it in so the newer style box fits . Either way it is sort of a rig if its a show truck might just be better workin out .

its best to dimple the frame !!!!! if you use spacers the sterring geomitry <sp? will be off and it wount steer just rite and the stress from the spacing might break the frame or break the bolts that hold the steering box on and that isnt a good thing to happin when your driveing it

I put steel spacers on a friends 67 about 12 years ago, has not had a problem to date. If I remember right they were about 5/8 thick, and I tack welded them. It was basically stock with 33s

Mine has 33's also. How do I determine where to drill the holes for the new box to ensure the linkage will connect to the arm on the 4wd front axle. I don't see any holes except where the goofy looking manual box is mounted and they are different.

Does any body have pics or measurements? Thanks for the help so far.........

the bolt holes sould be in the same place on both boxs and the frame !!!!!!! its been a while since i have did that swap but i am pretty sure there in the same spots and i dont think i had to drill anything but i did have to dimple the frame for the steering box to clear it and thats the best and safest way to do it !! not saiying the other ways wont work, just saying thats my 2 cents worth

Thanks, I'll be trying it in a couple weeks. It's hard to tell about the holes while the manual box is there, just doesn't look right though.

Thumbs down

Look Out.
I tried a '69 (C/10) power steering swap onto a '67 K/10 Suburban. Nothing but trouble. The steering gear kept on breaking 1/2" grade 8 bolts. It also leaked profusely, getting PSF all over the drivers side spring perches -- which caused the axle to shift position on the leaf spring. The worst thing was my steering geometry was AFU -- had the turning radius of the Queen Mary, especially on a left turn. I had to make an illegal left from the middle lane if I was to hit the right lane on a U-turn.
'67 was a weird year, it had the new body style but a lot of the old early '60s components. The pittman arm ran up & down, not left & right. Power steering was "Power Assisted Steering" using servo pistons to help the gear box pull thru the turn. This system is still available from Corvette guys, since they used it on 'Vettes for a long time. [Probably due to space requirements.] But expensive.
My solution will be to switch out the corp 10 bolt front end for a '77 K/5 Dana 44, which will use the later model power steering set-up as well as have power disc brakes.
But the sad thing about that Sub experiment was that when I JB-welded the cracks in my old steering gearbox and tried to go back to manual steering, it was never the same. We'd cut and welded the original drag link and the geometry was all off.
A front axle from a '69 thru '77 Blazer will have the right geometry for the later style Saginaw power steering.

I am picking up a 68 4x4 with added P/S next Sat. I think it used spacers. When I get it I can take pics and if your interested sell you the setup. It is a rolling body with no drivetrain other than the axles. PM me if interested, plus i am not far.

I spaced mine using a kit that has steel plate cut with the proper clearance for the box. There is also a piece of plate on the inside of the frame rail. When you do this you need to change out the steering shaft. The 67 and 68 use a solid shaft from steering wheel to steering box. The later ones have a universal joint in the shaft. This allows the box to be spaced out a bit from the frame. I also changed out to a later disc brake front axle. This allowed me to use the later drag link, etc.. I have had this setup now for 3 years with zero problems. Good luck!
