Converting to power steering
I have a 68 non-power steering truck that I would like to convert to power steering. The frame already has the dimple that is required, but I am unsure what all parts I will have to buy. Can anybody tell me ALL that will be required to make this swap. I was told I would have to change out the center link, pitman arm and coupler. Is that true, and if so where can I get the parts needed? Thanks for the info.

The following is a list of the parts you will probably need and an idea of what they cost to buy brand new. If you're buying used parts, you can get for as little as ΒΌ of the cost of new, but ... someone already used some of the life out of it.
Pitman arm for power steering - $40 2WD rebuilt power steering box - $225 Power steering pump/fluid resevoir assembly - $80 Mounting brackets for the pump/resevoir are necessary and may come with it. Also necessary are the two hydraulic lines that connect the pump to the power steering box. I think that's everything. If not, I guess someone else can chip in. I also have a '68 (shortstep) without PS, but with the dimple. I created another thread on this a while back (search forum for "dimple"). NOTE: I think there may be two types of pulley on the PS pump and resevoir, so ... just a heads up.

And the coupler (rag joint). The input shaft diameter is different on the PS gearbox. Pull one from a donor Chevy PU (can be up through early 80's) and get a rebuild kit (if needed) from the Help! section at the parts store.
You can also use a later model pump if you can find one with the right pulley. You may run across metric o-ringed fittings on the back of the pump. You can use a fitting from an old worn-out pump to retrofit to the non-o-ring hoses that are correct for your model year. The big fitting (arrow below) screws out from the rear of the pump and can be interchanged as needed. Don't lose the spring. SSOW ![]()

Your biggest problem is finding the mounting brackets for the pump. Finding a complete donor truck is the easiest. Late model pump mounts(73 & up) will not work with our truck's waterpump. (sbc v8). You can go with later waterump, but then need to put alt. on other side of engine.
What engine you got? As mentioned in another thread, you won't have to change the drag link, get a pitman arm for a 68-70 truck. BTW, many guys find donor a 73-87 truck, and completely change the crossmember. It bolts right in I've been told. This gives you a ps box, disc brakes, sometimes a sway bar. All you need is the pump and hoses. Be aware that it will be a 5 lug set up.

You may also need two-groove crankshaft and water pump pulleys if you don't already have them, and a belt. There's also a little clamp shaped like an "M" that holds the hydraulic lines to the top of the chassis.

Not to highjack the thread, but would a pitman arm from a 71-72 work in the 68, or is it specific to that year w/PS?

pitman arm has to come from PS box, using your manual box pitman arm wont work.
