Box in the two pieces there to the frame. Imho I would get some pics of the bolt on bracket I've seen on a few trucks. Goes from engine crossmember to frame.

 

I have a question about the drag link. I know its porpuse is the keep the axle from moving side to side, but when the axle moves down from the the frame doesnt the drag link pull it the the drivers side.?

 

It does, but its not noticable in most offroad situations. Usually only 1 wheel droops and not both at the same time where you'd really notice.

 

Is there any advantage to making the drag link mount as low as possible

 

On the frame end? That would be bad I think as the lower the mount the longer the bar/bracket which puts more stress on it.

 

You want the drag link and trac bar as close to parallel as possible to keep bump steer as low as possible.

 

Sorry i know this is old but im about to do this swap.
i have a 1994 f1504x2 with a 6in lift and a donor 1979 bronco.
i wanted to know if i can use the 6in radius arm drop brackets from my 1994 f150?

 

As long as you use the ttb radius arm brackets, yes.

 

Yes you can. I used the 79 drop brackets on my 95's frame. Just need to use the rear hole for the 94's brackets as the front and drill a new rear hole in the frame.

Edit, wait, are you using 94 ttb drop brackets or 79 radius arm brackets? Either way yes, just need to put them right for the correct radius arm.

 

I think the factory 73-79 radius arm brackets do a better job though

 

Karl, i think he wants to use the 94 drop brackets.

 

its the drop bracket from the ttd and they're thick and i like the way they look. i just wanted to make sure they would work

 

Also what C-bushings do I need?

 

Lets go with function first and looks second

 

True so what do you think?
