will cutlass coil springs work on a 1972 vista cruiser?

 

The front is the same as a Cutlass, have to be rated for whatever options the car had, engine type and all that as usual.
I hear of guys using the Vista Cruiser cargo coils on the rear of the regular cars but not sure f a Cutlass spring would work in a Vista? They still have have be stiff enough to hold the car up and the right height and all that too. They sell both types of rear springs at Rockauto.
I used the cargo coils and they don't make the car sit any higher or change the ride, they just get stiffer as they're loaded with the extra small coils.
