Hey guys, I know this subject has been hit before. but I wanna get some info anyways. I have a 66' F100 4X4 with a coil spring front end. I want to put power steering on it. I may or may not be ahead of the game. the truck has the original 352 in it. however I purchased a 390 out of a 72 ford f-250 I believe. the engine came complete with air conditioner pump and power steering pump, pullys and brackets. so what sorta gear box should I be looking for to meld with this truck and engine. what makes, years and models can I find them in. or is there aftermarket stuff I can find. oh after the 390 is rebuilt it will be going into the 66'. the Air conditioning pump will be turned into an on board air system.

If you go to the 67-72 truck forum there is a sticky about options. Myself, I used a 87 Toyota box and a pump from a mid 70's ford F150. My cost was, at the time less than $300.

 

There isn't anything.

Ford did not offer P/S on F100 4WD's until 1973, and thru 1977 (F150 4WD's) it's Garrison Power Assist P/S (ditto 1975/77 F150 4WD's).

Power Assist P/S uses the manual gearbos, has a separate control valve and ram cylinder.

There are next to no new replacment parts for Power Assist, and if you do find anything...the price will be $$-$$$.

Contact garbz2, he may know how to adapt the Ford Integral P/S first used on 1978 F150 4WD's (no F100 4WD's after 1976).

 

How about the 77 Bronco box?

 

thanks for the info guys. so a power steering box out of a 87 toyota will work? what kind of mods do I have to do to it. or does it virtually bolt right up.

I assume you mean P/S box. I haven't a clue whether it will work...or not.

Good luck finding one, it's rarer than hen's teeth.

1976/77 Bronco P/S gearbox is the same: D6TZ3504E (ID number on box: SPA-AU).

1973/75 Bronco P/S gearbox is different: D3TZ3504A (ID number on box: SPA-Z).

 

Doug , I used a box out of a 87 Toyota 4x4. When I got the box, I also took the P/S lines that run from the pump to the box.
I removed the driver side fender and inter fender for better access.
1. Remove the old steering box and the steering link that runs from the box to the drag link.
2. Place the new box in the same place as the old one. mark the holes that need to be drilled, drill and tap into the frame, or drill all the way and put in a bolt and nut.
3. The new box, the pitman arm has a stud, where as the old pitman arm has a hole to hook the box to the drag link. I used a piece of a drag link that came from a Chevy truck that had a hole in it, the hole has to fit the stud on the pitman arm. The steering link that came off, I cut that in half and treaded the the Ford piece and the Chev piece togather using left and right treads and a turnbuckel off a tie rod end, got from the tie rod end off the Chev. Thet way the length is ajustable. Sence I had the drag link off that links the wheels togather on my truck, I cut off the nonreplaceable tie rod end and treaded a new new and turnbuckel. Now I don't have to replace the whole thing when the end goes bad again. You do not have to do that for this conversion.
4. I used a P/S pump off a 75 F100 Ford truck. The P/S lines that came from the Toyota, you will need to cut the pressure line fitting off at the pump end and replace it with a SAE fitting that fits the Ford pump.
I mounted the cooling loop with the horn on the drivers side.
5. I had to cut the steering shaft @ 3" and welded the end back on. Have someone that is a GOOD welder do this. The input shaft on the Toyota is smaller, so when you put in coupler on, I cut the slit on the clamp that holds the steering shaft to the coupling and tighten the clamp down.
6. I used a pully off a 64 Galaxie, I just had one, but when you pull a pump off at the wrecking yard get the P/S pully off the crankshaft.
Let me know if you need anything else.

Oh that is perfect. thanks for all the info. I dont have to worry about the fenders and fender wells. The truck is an off-road pre-runner. so it just has skins for fenders. I was planning on using Hym joints rather then tie rod ends for better movment of the suspension and steering. again thanks for the info. if I need anything else I will let you know.

PS I have a 64 Galaxie also. it is a 2 door, 500. not the XL. it has a built 390 in it. my grandmother bought it brand new off the show room floor in 64'.

 

Cool, I have had my 64 sence 1973, it is not a XL ether. But I have used some XL parts in it over the years.
