77 Highboy power steering conversion
Hey Gang.....
Could anyone help me out with the list of parts required to change my Highboy from the leak prone, multi-power steering hose mess I have now to the power steering incorporated into the steering box; like on the newer trucks? Can I still keep the large external hubs? Any help or advise would be appreciated. Thanx BTV

Well BTV, your going to need
-a 6" pitman arm
- new drag link
- integral power steering box 3 hole or 4 hole
- the hoses that came off the box
- and some 1/4" or 5/16" plate to box in the frame for the box
Everything listed can be found on 73-79 Ford trucks, and yes you can still keep you hubs.

bob , call LMC in kansas(800-222-5664)and order their catalogue---it has very good pic's of the ps systems for the 73-79 and later trucks---you can visually see the difference(s)----You should see the pic's Mr. jc workman took of his conversion--they are very good and helpful---he posted them in his gallery---When you buy a steering box---get the one with (4) mounting holes----for the f250\350 4x4 work load---not the 3 holer----the steering arm on the left front wheel will work just fine-----the draglink that connects both front wheels will work as well----you will have to procure the short connecting arm\link that connects the pitman arm on the ps box to the steering arm on the left front wheel , good luck , fd

---When you buy a steering
>box---get the one with (4) mounting holes----for the
>f250\350 4x4 work load---not the 3 holer----
I was just wondering why you say to get the box with the 4 hole and not the one with the 3 hole? Is there an advantage with the 4 hole? I have the one with the 3 hole right now and all the parts to do the swap. I also have the steering shaft an u-joint from a 4 hole box and it seems to be a different length then the one on a 3 hole box. I do have access to the 4 hole box for free from a friend if that will be better i will use it. The 4 hole box is out of a 79 F250 4x4 supercab.

Well , Ford is the one who decided that a f250\350 4x4 would probably need a ps box with alittle more MOXY , given the fact that the rated workload for the front axle of an f350 4x4 is probably about 2,000 pounds greater than for a f150 4x4--vs--an f350------ON THE OTHER HAND-----I could be wrong!!!But , I believe that the 4 holer is the ps box that was origional equipment----I , personally , wouldn't accept anything less---also , if you know of a 4 holer from a 78-79 for f250 4x4 that is for sale i need to do the conversion myself----fd :-X11
