Frt. Brake ?'s

[ck5566]

I am working on a 70 C10 frt. 6 lug setup that my local 4 auto parts stores & all of my 8 truck restoration catalogs cant seem to help me with finding these parts. First part is a frt. brake shoe anchor pin " flat locking washer" that is indexed as to not allow it to turn when the washer is bent up to the anchor pin to a locking position, pic shows it. Second part is a "cork gasket" that when your backing plate is mounted to the Spindle just be for you install the frt. wheel Hub there was a cork gasket in place which wood stop any thing from entering inside the seal & bearings area. pic shows it. Any help would be great in finding these parts. thank you.
