Not so. Those rates sound closer to the springs for the 99/01. They're not the rates for the #85245 springs.
Here's a formula you can use to estimate your spring rates:
Spring Rate = ( Wire Diameter in inches^4 * 1470000 ) / ( Coil Diameter in inches^3 * Number of Active Coils )
where 1470000 is a constant representing the modulus of rigidity for spring steel
This is a simple formula that works for linear rate steel coil compression springs. If you use it to see what rate your springs really are, you won't have to rely on what the guy at the other end of the phone (or Internet) tells you.
EDIT: I just went out and made a couple measurements on my front springs, then plugged them into the above formula. The rate came out to 726.7 lb/in
