By the way, I have something important to add to this...
After over ONE YEAR, VALLEY SPRING WORKS hasn't lived up to their word and replaced the springs that they made incorrectly for me: http://www.vehicross.info/forums/showthread.php?t=4631
They've made many promises, but I never received a new set of springs.
I'm still out $270 bucks, and they don't seem to care.
I now would recommend that no one do business with them in the future.
EDIT: Their web page has been taken down, but I got their address and phone through Google's cache:
