im trying to swap a 78 d60 into my 74 f250 highboy but the steering bracket on the 78 is a boomerand shape and the 74 just a straight bracket do i need to use the drag link and steering arm from the 78 or the 74? confused need assistance some one please help

 

Does your D60 not have a steering arm? All you have to do is install a custom drag link as well as the steering ram if you have a power assist.
The d44 components will never bolt to a d60 so you will have to get a little creative here.
Any reason why you dont consider a power steering upgrade and a crossover conversion?
All of my trucks are better because of this upgrade. especially my 74 highboy:

 

I happen to be doing the same swap in my '75 and this is what I have planned out.The factory drag link should bolt right up the arms are roughly in the same place. As far as the axle and the ram setup well,thats a different setup.First off the 78 axle should have the shocks mounted one in front of the axle one in the rear,that will have to be dealt with.Also I like the ram setup,IMO the pitman arm goes in the direction of the framerail and not perpendicular reducing the stress on the rail.this becomes a problem when installing bigger tires or a winch/bumper setup.With the high steer setup there is alot of torsional load on the frame and alot of reinforcing to do.I used to work on alot of wreckers back in the day and the frame breaking from the "left to right"steering setup was very common as most wreckers back then had push plates overloading the front axles.Also most big trucks run the front to back pitman setup for the same reason.What I have planned out is to cut off the shock mounts,fabricate duel shock mounts,make a ram mount to go in place of the steering stabilizer(much beefier than the stock shock bracket)and use the drag link setup thats there.

 

Unfortunately the problem with the push pull steering system and lifted trucks is that the spring changes length during a normal suspension cycle, and the drag link cant change length.
This is called bumpsteer, and also prevents articulation. The turning radius is also limited by the push / pull design.
Notice that newer vehicles dont have this steering design any longer.
Good reason for this.
Vehicle with limited travel like the above mentioned heavy trucks can get away with this design, but smaller 4wd trucks that require some axle articulation really suffer when this steering system is used.
many folks like it, but it has its limitations.
