Is this dumb or brilliant? You decide.
Dumb, and here's why.
All mopar super stock springs are the same length. 56". Front segment 20", rear 36". That's true of the "A-body" springs, true of the "B-body" springs. That's why Mopar specs them by vehicle weight and not body style, and why you need longer front hangers to run them on a E/B body. SS hangers for E/B bodies are 2" longer to make up the difference (#P4120079). I ran SS springs on my Challenger for a bit, the longer hangers are required for E/B bodies.
The same pair of SS springs from my Challenger is currently holding up my Dart in the shop (temporarily), its a straight swap.
The problem is that the springs are too stiff because they're for a heavier car, and that's why you're not hooking. Moving the shackle mount will let the suspension travel a little more, but it's not going to solve your problem.
What part number is on the springs anyway?
