dana 60 in a a body ? well its a huge rear end , and cheap until you have to cut them down and get brakes for them , but you'll end up sending the same money cutting it n braking it . so other than its hugeness , you won't be breaking it , even with a blown or turbo'd /6 .this guy did his own measuring and he made a few that cost him , more machining time and a redo of his mods to the rear brake and axles fit to the rims he wants to run . so be careful what you get in to .
