I used the Mopar springs on my 69 RR and experienced the same problem many other have with them, they sag about an inch after use. Not sure if thats been fixed or not. I also used the AR engineering (which Mancini sells ) front spring hangers that have adjustable heights. Overall I liked the springs, they worked good in my car but it wasn't a track car.
To answer your question; yes they would be a good fit for your car and may sit higher at first. [img][/img]
