Spring Rate Question

What is the spring rate of the factory option rear springs on a 01 firehawk with the optional SLP Billstein suspension? SLP apparently won't tell the guy i'm trying find this out for. Also, what are the dimensions of the stock springs if anyone has them handy? I can measure mine but I don't have them handy at the moment. Thanks.

Thanks cool, but could you break down those numbers a little, they're not very clear on what's what.
