what year pwr steering is on my truck?

[66rat]

My 66 c10 had pwr steering when i got it and i need to put on a new pwr steering gear box but i dont know what year the gear box i have came out of. What is a common conversion someone might have used?

[msgross]

need pictures...

most of the boxes from 70's thru 80's are near identical. They did change to metric threads and quick steer ratios at some point though.. But the boxes look the same on the outside.

It's impossible to give an answer without a pic or two. All truck based power steering boxes from '71-'87 are identical in appearance on the outside. From '71 to about '81 they used an inverted flare style fitting for the hose connections. From about '81-'87 they used a metric fitting with an O-ring seal. There were also two different diameter/splines on the input shaft.

The Saginaw 605 is a very common box used when converting these trucks to power steering. They are readily available at salvage yards, remanufactured or new from your favorite local auto parts stores.

if they are identical on the outside what would i take a pic of that will help?

[66rat]

mine has a couple differences then that one in those pics. sorry i dont have a camera right now to take any pics w/

The pic that Tony posted is of a 4X4, so that may be some of the difference you see. However the box itself is the same. One thing you can do to determine the aprox year of your steering box, is disconnect one of the lines on it and see what style of fitting it has. See my previous post for the style types.

why do you need a new box? You know that you can rebuild them right? not for the faint of heart but very doable so i've seen. I picked up a kit from rockauot.com but haven't attempted it yet.

This is a box from an 86 chevy truck. It sure dose look alot better since I cleaned it up and painted it..

[66rat]

i think i've decided its around a 71 or so. i know you can rebuild them but i have heard from some guys at work (a gm dealer) that building those can be a pain, because something about the bearing on the inside and getting everything adjusted right. i just bought a reman today for a 71 and gonna see if it works

on some the shaft coming out of the top of the box which mates into the rag joint are larger as mine was. I found that out when I replaced mine. Mine was from a 75 or 76 4 x 4 suburban. that difference may not be in a 2 whl dr. though.

Here are a few more pictures of power steering conversions I have done on a few of my trucks. One is a 1/2 2wd, one is a 3/4 ton 2wd and one is a 1/2 ton 4x4. All of them utilized the GM Saginaw 605 box and the power steering conversion frame bracket kit.

I need a power steering gear box for my 1962 k 10 and have bought a frame bracket kit from 456 truck and they say use a Saginaw 605 but I can not find one .
Will any 4x4 Chevy truck Blazer or Burb work?
Any information would be appreciated.

[61K10]

yes it has to be from a 4x4 and any up to the late 80's will work

[williamdale]

Thanks 61 k10 for your quick reply. I found 2or 3 in a junk yard and was not sure if they would work.The maker of the support brackets said to use a Saginaw 605 and the only pictures that I have seen of a 605 did not have the 4 bolts and plate around the top of the gear box.
Once again thanks for the help.

Thank you for your help and I took a look at the dash that you did for the 27 caddy
that is some real nice work.
Thanks for your quick reply.

thanks. just use the same pump as box(same years) and you will have no problem with hose fittings. unless you are using orig pump mounting with short water pump. newer pump does not align with the orig crank pulley.
just got another dash job; putting a Circasian (french) walnut dash in a Morgan
