not truc actually, having owned and built a small block ranger on 44's, the weight of the ranger is a huge advantage to solid axle durability, especially in the mud, i left the eb 44 open in the front, with a set of moly axles and beefier u joints and NEVER had a problem with it, and the 9" can be beefed up aswell to take the abuse......
that ebing said, it would be MUCH cheaper to run 1 tons under it, id run personally a 14blt ff in the back with 4.88's and a detroit with a ford hp 60 up front, get the moly shafts for the 60 and leave it open(will really help save axles) also todo this properly your going to want atleast a 250hp small block, as a under powered motor can cause breakage aswell(getting traction when it should keep spinnin due to lack of power),
now for height wise your goin to want the complete lift kit for a 79 ford, atleast 8" (gives u about 12" on a ranger) and a 3" body lift. your going to have to setup a hydrosteer system if u actually want to turn the truck
you know......this could take forever.....
i think i should just post pictures of my 93 f-150.....you basically NEED everything i have done to it....hold on lemme get some pics
