[GD51LA]

i'm screwing my rocker cover and it needs the rubber i Ring that go on the fasteners, i rang nissan and they want $7 each (x20) is a bit much i think

are their alternatives out there?

I used genuine on my most recent build, but I've previously used cut down lengths of rubber hose and they worked fine too.  Changing the 20 year old ones is a good idea....

Just about anything up to and including neoprene roofing washers. Cheap, oil resistant and you can get them in a pack of 50
