Rear Spring Rates/RPO's?

[Playsinsnow]

After killing some time reading threads on suspensions, I was wondering if rear and front spring rates are identical for a model?

I have the 84s up front with the pink tag, but the rear tag is purple/lavender and reads "15207741" and "YNT". The rear squats more than I like when loading the back up with only a few hundred pounds, tops, and it has become worse over the years.

Thanks for the links Thumper

Guess my question now is are the rear spring tag colors identical to the fronts regarding spring rates? Meaning is the rear lavender tag spring rate equivalent to a lavender tag front spring?I'd assume so...
