$200-$300, $350 tops to have a shop install them...and they can do it in a day's time. $150 for the Mater Kit...and your gonna also need the:
Rear Trailing Arm Main Bushing Set
Shifter Linkage Set
Sway Bar Sets
And the Front Suspension Forward Extending Rods (forget their names)..their is a set for them too.

These are all extra cost.

I recommend while doing this to get some Brake Lines while your in their and buying a Larger Teg Master Cylinder.
