I am buying a 78-79 ford Dana straight axle and putting it in my 93 f150. do I have to change the coil towers or the radius arm brackets and what coil springs would I use? and what would I do about the power steering box and the pitman arm? also what rear axel would I use? my truck is 2 wheel drive and I am converting it to 4 wheel drive. I have abs in the rear axel only. do I eliminated it? do I have to change my booster or master.

 

you will need the towers and radius arms and brackets from the donor truck. for the 4x4 swap you can use the rear axle you have. you just need a different transmission and t-case and drive shafts

 

Make sure your gear ratios are the same

 

you dont need the buckets(towers),
you need the 78-79 coils, the 78-79 radius arm brackets.
stock steering box, 4x4 pitman arm,
here is one of the best steering setups that you can do with over the counter parts.
Stock replacement 1979 bronco left/right tie rod ends
AutoZone Part #s
ES2064L (left)
DS922 (right)
ES2066S (adjustment sleeve)

1995 F350 4x4 drag link & tie rod end (to pitman arm)
AutoZone Part #s
DS1068 (drag link)
ES2615R (TRE to pitman arm)
ES2012S (adjustment sleeve)

if your going to go with lift coils then you'll also need a drop pitman arm. (for your truck)

 

thank you so much for all your help. I will post pictures when I am done
