Hello, I´m thinking about getting these springs into my `72 240Z, but i want to find out some more details about them and if they suit my driving needs better then the Eibachs. I could get almost any info (beeing a german engineer makes some things easier), but i need the Vogtland Art.-No to identify them. Could anybody provide me the number written on them? It has to start with a "95" and is 6 columns long. Thanks.
