whiterino's beef

where can i find a keyed washer for a dana 60? the ones that go between the two nuts that thread onto the spindle. no luck at any auto parts store. im at the point where i am about to go make/mill my own but am trying to avoid that since im lazy.

I am doing a project for my marketing class an di chose Interco for my company. I need to know how many people have Interco tires on their rigs. If you dont, please mark the no option on the poll as i will be needing a percentage. Thanks
