X body suspension question

[vintageracer]

I know the 1975-1979 X body cars (Nova, Ventura etc) all use the same front subframe as the 70-77 F-Body cars. My questions relates to the rear suspension on X body cars.

Is the rear suspension the "same" as the rear suspension used in second gen F body cars?

By "same" I mean same rear suspension pickup points, exact rear suspension mounting geometry and a therefore a direct exchange of rear suspension related parts. I know the design is similiar. I am interested in what if any rear suspension items are a direct swap from a F body to a X body.

I look forward to your responses!
