1978 Aspen Super Coupe, what's underneath them?

I parted a Super Coupe not long ago. I wanted the engine & wheels for myself, the car was rusty.

The car had a 8 1/4 in it with a 3.91 Sure-Grip. It had been raced some at Maple Grove & on the street also way back when. No fender tag or broadcast sheet, so not sure what it had originally.

The K-member & transverse torsion bars were scrapped, no interest from anyone at all.
