Leaf spring advice

My 74 Duster is a street car using 002/003 springs in the proper location. It rides just fine, sits pretty level and if they put the *** end up too much just add a lowering block. Don't be afraid of Super Stock springs, however I think there are cheaper options and it is true, Super Stock springs were intended for drag racing so if you are not drag racing then why bother. I bought mine a long time ago cause I thought I needed them. 10 years later the car has yet to make it to the track. Maybe this year though!!!
