does anyone know of a 4-link complete kit that will go in my 87 IROC that will soon have a ford 9" rear end?

now some questions:
if i have a 4-link, can/will i have sway bars, torque arm, trailing arms, panhard rod...ect? or does the 4-link eleiminate the need for all of those?

 

you'd not need torque arm, you have panhard rod but not factory arangement, you'd have to back half the car and 4 link isn't the best street set up

 

what about ladder bars, would i need to back half it?
