Washer size for oil spinner on 64 cl72?

[mips]

Anyone have a photo or dimensions for the washer for the oil spinner/shaft. I pulled off the side cover to clean it out, found the tensioner bolt finger loose(glad i took it off!) an realized there wasn't a washer on the oil filter spinner like shown on the diagram. I am pretty sure I will have a spare somewhere (I've got parts from 2 other motors), but not sure what to look for. I've found something that kind of fits, but know I need to get it right! Any help is appreciated!
