This is supposed to be off of a 79 highboy. I want to use the power steering box and the axle with the disc brakes. I’m going to shorten the axle.
What else do you gurus see her that I’m not?

What's the BOM on the axle tube say?
98% that is NOT the steering box you want. That is a push-pull steering box, the 4x4x2 steering box is a crossover steering box (side to side). Best I recall they are different.

"Highboy"...I don't think so. That basically was just a customer derived term for the 1967-1977.5 F-250 4x4 trucks with the positive arch leaf springs, which became negative arch in 77.5 and lowered the trucks about 4 inches. It's easy to spot them from a distance due to the divorced transfer cases and long front driveshafts. FWIW, all of those trucks were also 8x6.5 wheel pattern applications, so that looks like a 5-lug HP D44 from maybe a F150 extracab since it has the leaf springs up front. I don't know what that steering box is, but it mounts to the inside of the frame and looks a little different than my '77 F150 box.

So, axles is good but I have a steering box for the scrap yard. I’ll look at it closer for numbers.

That’s most likely an F150 super cab Dana 44. Some what rare that they were leaf sprung but half ton outers on a 3/4 HP 44 housing. The knuckles are unique to that front end since they are 1/2 ton but run a flat top 3/4 ton steering arm. The 78-79 F150 super cab and F250 super cab were both on the 3/4 style frame. The steering box, motor towers, shock mounts, proportioning valve, leaf spring mounts, and stabilizer brackets are all worth money.

That’s a $300 steering box (78-79 F250 style) and probably a $600-$700 front end.

As opposed to narrowing you could run those outers on a Bronco Dana 44.

I am going to say 75 -77 f250 standard duty dana 44. They made a heavy duty that was 8 lug. A very good axle to narrow. Should have 1/2'' thick axle tubes. You will need to get some wedges to use the arm type suspension.

I've spoken here many times about my years in a Ford assembly plant,30+ to be exact. At the plant where I worked we built F series pick-ups from 1973 till 1982 then came the retooling to build Rangers and Bronco II's. In those years that we built the F series trucks we only built regular cab trucks,no super-cabs or crewcabs, and no step-sides, all were F100- F350. Bax, you may be right in your post but I don't ever recall seeing a 5 lug axle in anything other than the half-ton F100 and F150's. If I'm wrong I stand corrected, That was many years ago, so be kind and not chastise me too hard, my memory ain't what it used to be.

That axle is closed knuckle and not 5 lug. The cross member and steering box are also 78-79. The only 1/2 ton to come with that knuckle and steering arm was a F150 super cab axle. There were some of those knuckles for sale in the classified section a few months ago. Pretty rare.

Well, maybe I can find someone who wants to trade a bronco appropriate Dana 44 with disc brakes for this set up. Here are some more pics to keep the debate going. I couldn't find any numbers on the diff. Somebody was either trying to fabricate something to reinforce this. Welded in plates everywhere. It also came with the front drive shaft and another set of springs, wedges and U bolts, maybe from the rear.

I tend to agree with you but it is a high pinion and appears to not be a closed knuckle design. It is a 5 lug hub witch would put it on a f100 ? Were all 150's radius arm? This is leaf spring so I don't think it is from a 150. It is odd to see a 5 lug on a 250. Most of them were 8 lug as I remember. Hell I don't know

It is an F150 Supercab from the late '70s

X2 I have a couple sets of those knuckles and have sold a couple of sets here over the past few years. The Super cab F150 knuckles have the highest factory steering arm and I've been told they are what the Duff knuckles are based off of. I can verify it for you if you can get the numbers off the knuckles for me. They used to be in high demand by the Jeep YJ guys that wanted to go with full width axles.

Thanks. That’s a plate bumper I just took off my daily driver. Went back to stock. I’m going to put it up for sale.
