has anyone ever replaced the gasket on the 650s rear diff drain plug. Mine is a little bent and is leaking a bit. Is it the same thing as a washer at a hardware store? because i really don't want to order a part and wait a week and pay 3 dollars when i can buy it for a dime somewhere else.

 

anyone know?

 

It's an aluminum gasket. Replace it or put a little silicone sealer on it.
