T3 Camber Plates

[AadosX]

I have a set of camber plates here and am wondering if they will work on a stock type strut/spring combo (KYB GR2/Eibach Prokit) on an S13. I've read something about a need for some type of spacers which I do not have. Are the spacers neccessary?.. and if so, does anyone sell them?

Thanks,
John
