Your Nova donor sounds perfect.

I was told (by someone who claimed to have done it) that the Nova rear (up to '78) leaf spring perches are perfectly spaced to fit our ADs.

Turn the springs around to center the wheels in the wheelwells, and GO.

I have not confirmed this yet, but I trusted his word enough to buy a rear set up for a Nova. It's sitting in my garage, waiting for me to get the frame stripped and powdercoated. Just haven't got to it yet.

If you get it installed before I do, could you let us know "for sure"?

Hope this helps.
