Air shocks are a patch. I've seen MANY with the rear shock mounts broken after air shocks. The weight of the car is suppose to be supported by the springs. The shocks are there to snub the spring so it doesn't keep rebounding when it flexes. You're putting the weight of the rear of the car on four half inch bolts. Not a good idea.

The rear leaf springs are relativly cheap anymore. Get a set of springs and shackles and do it the correct way. You'll be glad you did.
