Ok. Im installing my rear grantelli motor sports coil over kit on my 90 mustang and Im using kyb agx gas adjustable shocks. I cut the dusk shroud off and I went to slip the adjustable screw pirch the spring sits on and it wont slid over the bottom of the shock? It does sit all the way down on the shock, right? I need help! Maybe the kyb shocks arent compatible with the coil over kit? Maybe I should just get koni? What are you using?
