....another suspension question

73 Dart Swinger (318-904-7.25) running 245/60R14's.
When I bought the car a few years ago air shocks were already installed and I'm looking to get rid of them. I've heard some people are using SS springs etc. The wheels are Crager, no issues with backspacing or clearance.

Are there any recommendations for rear leaf springs without using airshocks?
