Will dana 60 fit in early a body?

Yes, the factory axle is a 7 1/4. I was on the Moser sight pricing out an 8 3/4 replacement. The price of a Dana 60 from Strange or Moser is about the same price of the 8 3/4.

I am going to put a mild 408 stroker in the car and will not need the added strength of a Dana...but if they are almost the same price I am tempted.

Go with the 8 3/4 it will handle anything you throw at it with the right parts. Plus it's a hole lot lighter than the dana.
