Can someone shoot me straight on an idler arm question?

Appreciate any help fellas. I pulled the 67 k frame out of my barracuda. I replaced it with a 73-76 out of a 360 Duster. It came with lower control arms and factory sway bar. My understanding is since I'm keeping my 67 steering box and pitman, the drag link from the 67 must be retained. I bought a new 68-72 idler arm because of the 67 one year only curse. It looks like it will mount okay, but it came with fiber and metal washers. I have no idea what they are for. If you can advise...
