Okay, I've been going over threads here and wanted to see who had what combination of springs on their car from the factory.

I purchased a set off a 1991 Formula that had BZW (14029398) front springs and NNL (10018091) rear.

I hoping to get an idea what combination GTA's, Trans Am's, Formula's and Firebird's came with. I found this chart below for FE2 and F41 Option Codes:
