Damaged Pressure Plate Straps

Z bar and pushrods all stock, new bushings so it’s not the linkage but thanks for the thoughts. I’m still not sure how only one of the straps could be damaged but it sure was. I had the standard B&B three finger pp in it for 25,000 very hard miles with no problems. Wore the friction material off from high rpm launches but that’s my fault! This is just weird, wish I could figure it out.
