When I originally posted these I wasn't sure what springs they were, but I found out that they are BBK progressive rate lowering Springs and will work on 79-04 mustangs. I stopped by BBK on the way home from FFW. These retail for $169.99. They are part# BPWPR100. I will sell them to a Wickedstangs member for $80 and will charge $50 if you want me to install them for you. LMK,
