How many of you who own or have owned a big brake car and have had the original front and rear metal dust covers for the backing plates? I've heard that the rear covers have wrinkles formed in the metal but what about the front? I have seen 2 sets of rears and both had the wrinkles like the ones on ebay. On the other hand, the two sets of fronts I have seen don't have wrinkles in the metal. What is correct/original and what isn't?
