Before people start flaming you I suggest using the search button. This topic has been coverd 100's of times.
Here is just a few quick pointers though.
Most common
front axle used is a 1977-1979 ford dana 44hp.(Ford because drivers side drop)
Most common
rear axles are Ford dana 60 and Ford 9" depending of course horsepower and personal opinion. Changing the rear axle out will mean adding a new sensor to the pumpkin for speedo calibration.
U could use a hole front suspension system out of a full size Bronco incorperating the axle, radius arms etc.
There is a ton of info out there but if you have another Q then ask and I'll see if I can help.
