Rocker cover gasket fitting question

[Tonka]

Hi there! First time back in a while, I need to get the Surf going again. I ordered a replacement rocker cover gasket....just having looked at someone else's engine rebuild thread online, it shows that the gasket has metal collars fitted into where the bolts clamp the cover to the head. I'm not sure whether the gasket I've removed and binned had them...question is should I have these collars/spacers? It's an LN130 2LTE 2.4D.

If I need them, would anyone know the part number?

Yes use spacers. They prevent crushing the gasket too much. Also be careful tightening the nuts and bolts. I did measure them years ago but forget the size now.
