and have a smooth ride and what kind of coils should i run in the front of my 66 impala fastback please i need the information thanks
welding cups on is ghettoi say run springs from the front of a regal or cutlass in back, and springs from like a 4x4 in front. but dont cut em until youve seen how much they compress when you lock the car up. and also, once your satisfied, WELD the cups on. "stock" springs tend to open up on the first turn after a while, so weld em so the cups dont sink in.
