Has anyone ever put 4wheel drive under their 56' shortbox f100? i would like to have advice on what would work best if anybody knows...thanks

 

i measured up a 80 bronco and it is 117 in long. i figured i might cut just in front of rear shackles to get 111 in. the track is within spitting distance of stock. it would require a shortened drive shaft, but other than that i think that is the best bet i found. the only other concerns i've thought of is engine placement in the bronco, but i may measure it up when it warms up outside(no garage!)i also concidered a ranger, but it seems you need to get into 99 and newer ranger shot wb is 111 in
