2x4 - 4x4 = no sweat
P45 -
I did this 4x4 conversion on my 74, which as far as I can tell is exactly same frame as my 93. I took the engine crossmember from the 4x4 rig and carefully marked the holes on the 2x4 frame, drilled, and bolted it in with grade 8 bolts. Then took all the spring hardware and bolted it up after grinding off and punching out the big rivets. Don't forget the T-shaped bracket inside the frame for the rear shackle mount of the front springs. I converted to a dually front and rear, but the springs are same-same.
Use Skyjacker SoftRide springs. 2" lifts will give you close to stock - I went with 4" and I love it. I have a 6" set in the rear - check out my gallery.
Steering - 4x4's have an additional big honkin' plate that bolts between the steering box and the frame - and the pitman arm bolts up 90 degrees to the frame (on a Dana 60 it does, not sure about a 44), and the drag link connects downto the steering knuckle.
It sounds like a lot but it was really pretty easy - just time consuming, and it loks great - check out my dually in my gallery. If you want I can send you the digital pics of the conversionand major pieces-parts.
I'm also going to swap my 93 CTD into the spot where my big block 413 in the dually currently is... .
Good luck,
