I need help identifying what coilover are on my car. I have a 92 RHD rx7 Twin turbo from japan. The coilovers are non-adjustable, purple body, but I can't find any name on any of them. The reason why I am trying to figure out what they are is one of the front spring is broken and I need to replace it. There is a number on the black front spring #S63-100-200. If anyone can help with this that would be great. Thanks
