I have a 292 in my 55 Crown and and sets on 215X70X15 tires.  Would like to fine new front coils springs for her.  Looking for best place to find springs and what information do it need in my search?  Presently from the ground to bottom center of fender measures at 24 inches.  I know the trend is to do low but it seems to low for me, but rides and handles good. I really do not know what the stock height should be, but I like to bring it up. Please help with your input.
