Perhaps you need to change the thread title to NEWBIE SAS QUESTIONS ONLY instead

Maybe, as ford switched from 1310 to 1330 that year so it could have either so youll have to compare the two and see. Of course different transmission combinations would change the driveshaft length so there theres good possibility that it wont work anyway. This applies for the rear driveshaft as well. Most likely the 79 front dshaft wont work, and no way is the rear shaft gonna work up front.

Tie rod and lower coil buckets

What size tie rod ends works with a 79 ford dana 44 from an f150. I am trying to order some but don't know what size. I ve seen where people have used the complete tie rod and drag link set from an 90s f350 and ive fond a set pretty cheap but wanted to know if they would work without any other mods. Also the axle I got didn't come with the lower coil buckets so I was thinking I could make them. Does anyone see any problems with that? I am using 79 coils. Looking at a pic of them it looks like the buckets have a indention for the end of the coil. This is the only problem I see. And one last guestion, Why do people move the upper coil buckets forward an inch?
Thanks for the help
John

I mounted my upper buckets as far forward as the frame would allow, like most everyone else who has. This placed my tire dead center in my wheel well.

If it was + or - one inch, it wouldnt be centered.

Easy easy question:

When swapping a 79 Front suspension to a 80 Bronco, the only serious fabrication is building a new transmission mount, upper track bar mount and track bar, correct? Everything else can be adapted to fit with moderate work?

I've been looking and looking, but everyone is using lift springs, longer radius arms, etc etc. I'm just going to swap stock stuff over.

Agreed, the shape of the frame will only allow you to go an inch anyway. best to take it, since not only does it help center the wheel, but it lessens the chance of the tire coming in contact with the firewall.

Youll have to do some measurements, but most likely youll need to make a new xmember underneath the motor. At 4" of lift it clears (check out bossind's swap), but at stock height im betting the axle will be hitting that xmember pretty badly.

Ok thanks. I can still use the same drive shaft right?

You can use the stock dshaft. Some people have had to use the pinion yoke off the TTB since Ford upped the ujoint size. I cant comment on this since i went right to a D60 & custom dshaft.

As for steering, you can use a F350 tierod & draglink. the chevy rod ends are larger (read=stronger), but you also need to ream the knuckles & pitman arm to fit the larger ends, as well as make custom bars to thread them into. The specifics of the swap are easily found by searching under "Chevy TRE" IMO the way to go if running big tires (37+") on the rocks, altho its not a requirement.

You want to focus on the caster, and it should be around 4*-5*.

And coil buckets, unless you use the adpaters.

I'm gonna be running a WHOLE 79 front suspension. Coils, Coil buckets, everything.

Would 6" of lift clear the crossmember? he says he has some lift springs he'll sell me too.

I believe you will need the '79 coil bucket.

Yes, that will clear. I am running 4" leafs and a slightly trimmed crossmember, and I have room to spare.

For the centerlink I used Moog DS922, ES2066S & ES 2064L. These are stock steering parts on the '78-'79 Bronco and F-150. They will bolt right up.

For the draglink I was using Moog ES2011R, ES2012S & DS1068. I have no idea what these are off of, as I think I got them by size vs application. These parts are about 1" to short, so I wouldn't use them long term. I have since gone to DOM tubing and Moog ES380L & ES2010R ends.

This gives you more clearance under compression, as the live axle will travel further than the TTB.

I thought that the radius arms would move it forwards under compression anyway?

No, it moves it rearwards. The radius arm is the fixed point, so there is no way it can move forward.
I'm not that good at geometry, but if you hold out your arm and pretend your elbow is the radius arm and your fist is the axle; whether you go up or down, your fist can only move rearwards. Make sense?

As stated above you will want to re-use your Yoke off the d44 TTB chunk and swap it on the 79 axle.
The chevy TRE's are readily "available at most all parts stores, here is a great resource for "why" and "how"
