My Cousin decided to scrap his 81 one ton leaving me to deal with the parts. Needless to say the Dana 60 front and 14ff rear are going into my K-5 unless I decide to do something weird. I know I have to move the rear spring pad mounts out. How about the front D 60 is it a bolt in or is there alot of mods to do? How about swapping the Hydroboost brake system?
