dana 44 swap

Hi guys,
A local shop has an EB dana 44 he tries to sell me every time I go in. I finally caved and asked him the price and its $350 for the axle and everything off a full size 44 for the disc brake swap. Seems like a good deal to me. What else would I need to put this under my 66? I think I need the tapered bushings BC Brocnos sells to use my existing steering right? Its the 3 way adjustable from Bronco Graveyard and only about a year old so I'd like to keep it if possible.

1966 U14. 300 "big six" efi, 3-on-the-tree, uncut rears with a 3" body lift and 3.5" bronco graveyard lift. 33x12.5 cooper discoverer stt. Not pretty but pretty fun

A dana 44 trak bar. The one from the 30 usually hits the front cover of the 44.

What year is the 44 out of? 76-77 knuckles are different, wider.

It's a drum brake 44 so earlier then 76-77 I'm assuming. And no idea what year the full width axle the brakes are coming from is out of.

The full size 150 knuckle is different than the bronco. steering has a bigger taper rod end and the steering arm is in a different place I think its wider.

Ok I guess I better go back down there and see what the axle is off of.

I think you had it pretty much correct. If it's an EB housing, it's going to fit an EB directly. If it's the full size knuckles from a '76-'79 truck, they bolt right in from the ball-joints outward, and all you need is the tapered sleeves you mentioned (we have them as well) to let your existing tie rod ends fit. If you ever need to replace the rod ends, you can update them to those with the larger taper so you won't need the shims/sleeves.
You'll also need the proper brake hoses to adapt the calipers to the existing EB hard lines (if they're still on the axle housing?), but that's easy. We have them in braided: http://www.wildhorses4x4.com/product...co_Brake_Hoses or you can use stock rubber ones from certain Ford trucks.
Or if there are no hard lines, you can simply use the '76/'77 hard lines and soft hoses. Makes future replacement perhaps a tiny bit easier.

One advantage of the Ford disc setup is the larger register bore that allows the use of the larger heavy-duty axle upgrades with the bigger u-joints. You no longer have to remove the knuckle to install them.

Obviously you will have to verify the gear ratio as well, and match to your rear if needed.

Depending on if you have a suspension lift, this is your chance to upgrade the C-bushings if you have not already. Otherwise you can use the same ones you have now if they're in good shape.

All this begs the question though, of what you are going to be doing with your Bronco and what size tires you're running.
The bottom line is that the 44 is stronger than the 30, but the other half of that bottom line is that you don't need a 44 if your use doesn't dictate that.
So while that is a very decent deal I'd say, you can also save all of your money if you don't really need a 44.

Truck has 33" tires might step it up to 35" at some point but not anytime soon. Used as a weekend driver with probably 40% of the time off-road but nothing super technical. I probably would never break the 30, but I want disc brakes and my 30 has something going on; its got a lot of positive camber and rebuilding the kingpins didn't seem to help. So I figured this 44 would be about the same price as adding discs to my 30 as long as there were no "gotchas" I was missing.

Sounds like a great reason to grab a 44 then!
Like you say though, as long as it turns out to be as-advertised and in good shape. Definitely has some advantages.

Good luck.
