Welcome back to the fight Jason. Tamraz sells JRS springs. I have their 4-leaf Z28 replacements in my car. Fairy stiff, but not bone-jarring. Decent quality. Certainly better than my sagged out base model originals. The 5-leaf stockers have a softer 89 lb/in rate. JRS also makes a 125 lb/in 5-leaf F41 replacement model. JC Whitney also carries those springs and IIRC reviewers there were reporting that JRS recently started producing them in Michigan again (mine were made in India). The reviews also state that the newer springs don't have a pre-installed front eye bushing (mine did). Might want to read the reviews at JCW for the latest info. Let us know what you decide to get.
