I have a 1975 C-100. Lost a blade on the 36" rear discharge mowing deck. The part I am having trouble in finding is #1336 (dome washer). Has anyone found a suitable replacement or a substitute? I was wondering if part#113134 (whizlok bolt) would work or if a nord-lock washer pair might work? I also found a similar dome washer at

I'm not sure if that washer would hold up to the torque needed on the bolt.
