Brake part question

[Kozmo]

Taking apart the rear brakes and ran into some damage on a part--and because I only know enough about brakes hurt myself I thought I'd better ask just to be sure.

Part # 6 on the diagram: "Anchor Pin washer"


Left rear had rotated so the brake shoe metal was mashing it--and it had actually been able to rotate out of place so the tab was above the shoe--though it looks on the part like it's been rubbing on the drum,I don't see a corresponding mark on the drum so possibly the full rotation happened while I was fiddling.

I can just flip it (after a deburr) so the good bits are at the top instead of the bad---and I assume this part doesn't do a heck of a lot except help with the brake spring placement and and keeping any rubbing of the springs off the shoes a bit. However, I thought I'd better ask if it has some other important purpose for which that damage might be a bad thing.

If it is wise to replace it--source?

Any feedback?

Thanks

Left damaged one top, right one bottom
