You can fit 35x12.5's with the right amount of backspacing on these trucks (i did on mine anyway, when i still had the dana 44 TTB leafsprung)

 

Just to beat fishy to the punch. You can fit anything with the proper application of a sawzall.

 

Here is an article that I pasted together from information I got from a variety of sources.

You should also check out this site: http://77cj.littlekeylime.com/Dana44.htm

Also, check out http://www.pirate4x4.com and see their solid-axle swaps forum.

Here is some more chat talk about this swap: http://www.fullsizebronco.com/forum/...ad.php?t=24977

Also do a search on this site for more. This has been talked to death around here and other sites. Where this parts list says 94 just use the year of your rig. I got this information from 78F3504x4 here on this site.

-78 F150 Dana 44
-78 lower coil cups
-94 F150 upper coil buckets (stock)
-4" lift Skyjacker coils for a 78-79 F1504x4
-90 F3504x4 drag-link
-78 F1504x4 tie-rod
-78 calipers
-94 brake hoses
-78 brake line (on the axle)
-78 ford hubs
-94 F1504x4 pitman arm (Rancho drop)
-4" lift shocks for a 94 F1504x4
-78 F1504x4 radius arms
-78 F1504x4 radius arm brackets
-custom 18" adjustable track bar ($40 from local race car shop)
-custom front shock mounts (single)
-dual steering stabilizer I rigged up from my old TTB one.

We welded 1/4" thick steel to the engine crossmember before drilling a 3/4" hole to mount the track bar. I used the track bar mount on the axle, and it lined up perfect to the crossmember. Its been a while, so I can't remember everything. If you want I can take some pics and send them (digital). Seems every swap I see was done different. Later man!!!! Steve

Also, some other stuff:
-4 degree c-bushings
-front 94 front driveshaft fit perfect on the 78 axle
-the 78 driveshaft u-joints are the same as 94
-If you like the dual front shocks, you can get the bracket from a 77-96 bronco

As soon as I can afford this swap, I will be changing my 94 F150 to a solid axle truck.

 

i loved my sas....kinda wish i hadn't sold it....my sas design didn't gain any lift, but it could have if i had wanted it to.

 

I'm going to give my rig a bit of punishment and I want things to hold up, I've already torn up a D50 so I'm just worried.

 

Thanks for the info Ponyracer
