I have a 1956 Century that I pulled off a farm couple weekends ago. In getting off the ground and some tires that hold air I have discovered that I am missing a Rear coil spring. Kanters I think has them put they are little pricey. What donor car from the bone yard could I use that would have comparable springs? A big Cadillac or something. Also were could I find the Spec. one these and other springs. Thanks :bglasses:
