Yeah im in the planning of a 4wd conversion on a 79 crewcab. Ive finally decided on coils and longarms (4 to 5 ft radius arm) up front. Im a welded and fab guy by trade so its not gonna be as hard on me as the average joe. But i will say ive been planning for id say 2 yrs? Sounds bout right Ed? 75F350 has alot of good info to provide and Ted has done it. Listen to these guys and ill chime iin where i can. Front axle bracket drawing is at the machinist now so i may get started soon.
