Newbie Dumb Diff question

Not a dumb question at all.

Dana 60's were used in a wide variety of vehicles including alot of trucks. More than likely this is what you are seeing advertised for that low of a price but what the heck, why not call, you might get lucky. I will say if you don't need a Dana (i.e. You have alot of H.P.) a 8-3/4 will do you better because it's alot lighter and will eat up less horsepower. Now if your running 600+ HP a Dana is definetly in order.

To answer your question about rearends being meant for specific vehicles, yes there were certain types used in different vehicles from the factory but that don't mean you can't use any type you want in your car. Lots' of guys use Ford 9" rears in Chevy's and Mopars cause they're a dime a dozen and tough. It's just a matter of how much money and work you want to put into making it fit in it.
