Mono spring question
I have two I am going to replace and I pulled the used ones I bought out of the box this weekend. I noticed a couple of codes/markings, one had FHA with 1-1 below the letters and the other had NYR with a 6 below the letters. I've seen charts posted (don't fully understand). My question is will they work on my car? I've seen the different rates from base to Z51 and I'm hoping they will work for my set up. I have a base '96 with stock ACdelco shocks(1 of the 1st things I did, should've done the Bilsteins) and I plan on doing the bushing.
Thoughts?

You're good to go. Rear springs fit all C4s: the 1988 changes in suspension did not require a different spring dimension. So that NYR spring is fine in any C4. It has a rate of 326 lb/in. The front springs are different from early to late cars, so you have to make sure the front spring for your 1996 is from an 88+ C4. According to the chart I have, an FHA spring is indeed from a later C4. It has a rate of 532 lb/in.
