lil' powersteering question (77 bronco)

sup fellas,

got a question for y'all.

my bro-in-law has a 77 bronco and i'm lookin for a powersteering box for him.

he says that he heard about using a late 80s toyota p/u box.

is this a possibility? if so, does anyone know the years?


thanks y'all, and have a good one,

malphrus

I believe people are just using 86' and up IFS boxes. I have heard, however, that the p/s kit sold by Duff uses a Nissan Frontier box and that it's a bolt in! Well, That's what I heard anyway ..........Hans

I'm not sure about the toy box. I have a F150 2WD box on my 68. Don't know if I would put that little box on my rig. The pump might work but the would seem alittle weak for me.

Some people swear by the Toyota boxes and from what I hear they hold up fine. The bad it's about the most labor intensive of the three here and IIRC the pitman arm creates some issues.

There is the 78-79 Bronco box that fit's nice but you have to swap out the worm gear from a 2wd box to make it spin the correct direction. The bad is the boxes are getting hard to find cheap and you have something that is far from off the shelf so if it breaks you are searching junk yards for parts.

Another option is the 70's F100 2wd box, the box hangs below the frame and if you don't have a lift it creates issues and you have to build or buy a bracket to mount it and you will need a new drag link because it moves the box to the outside of the frame.

I think the Toyota box involves cutting the frame to mount it, the 4x4 Ford box is just about a bolt on (you have to drill a hole) and the 2wd Ford box is build or buy a bracket and then it's maybe drill a hole but just about a bolt on.

Ok so now for my opinion, the Ford boxes are the way to go because you can easily adapt the column to the box and the Toyota will be more work and it will be easy to get hoses made from a Saginaw or Ford factory pump to the ford boxes and the Toyota might be metric and harder.

I think any can be done and the 4x4 box is the best bet followed by the 2wd box and then the Toyota.

I have parts for the 2wd box swap (box bracket, track bar drop bracket, and tubes for the 1 ton Chevy TRE steering) if interested.

Hope the info helps.

Was the '77 originally equipped with PS? Broken sector shaft? If you have a good box and sector shaft send it off and have it rebuilt, but I'm guessing you don't or you wouldn't be posting up...

I remember a while ago someone swapped a Frontier box on their EB on another mailing list I was one. Was a pretty close fit.

As for the strength of the Toyota box, scroll through the Toyota forum and see how many people are running them with big meats.

nah, his didn't have ps stock.

i know nobody runs the p/u box in cruisers, just b/c they don't fit, but otherwise....

seems to me the toyo box would be the best and cant be that much work!

I have a 69 with a F150 box,they mount to the inside, you'll have to buy a drag link no matter what and the duff boxes and stock boxes are way too much$$$

any IFS box should work and they dont hang down like the F150

also , use chevy 1 ton tie rod and drag link ends, drag link mounts on right tie rod ,the stock setup mounts toward the center causing it to bend, have rods made and reem the knuckles from the top so you can install tie rod from the top gaining approx. 3"
