9" spindle hardware

Looking for the front-spindle hardware for front 9" drum brakes. I'd like 2 sets, if possible. Converting to race discs, and the chassis guys threw away the parts that retain the drums. I'm thinking that everybody threw this stuff away. I need the 11/16" threaded stuff. Nuts, retaining washers, and castle-type cotter-key stamped nuts

Thanks, Mike.
