I have a 65 Super stock race car I have been building. Would like to take a singel coil out of the front springe. Have a 455 riding on top of nailhead springs. Can any one tell me how to do this prosideure? do you cut out a coil in the middell and weld ends back together? Or cut off the top and try to bend in a new seat? how much drop will a single coil give?
