Hi Mrozz,
Like Ben said, we need more info before we can help you.
This is because there are many companies making kits. They kits can vary greatly in the design of the chassis and susspension set up.
So to be able to help you at a minimum people would need to know which company manufactured the kit ie: Robnell, DRB, Classic Revival, RCM etc....
If your not sure then try uploading a picture of your car and someone will be able to tell from the picture.
