So im gonna go look at a Bricknose F350 4x4 7.3l Auto for a parts truck. Planning on putting the front axle in my 89 F250 to get rid of the TBB Dana 50 (need to verify the ratio). From what i have read on various boards it should be a bolt in operation, using the outers from my D50 on the DRW D60. Not really sure if i need the 350 spring hangers or not......Just looking for someone more mechanical than me to voice an opinion and offer suggestions...Thx
