Baffle wire seals

Does anyone know where to buy the plug wire wire seals that attach to baffle for the top plugs? I followed Van?s instructions for the cutout but then realized I probably should not have and bought some firstVan?s says they come with engine, but I?ve built my own power plant. The cut out is a 3/4? dia oval. The ones at acs look close but not sure.

Plug Wires

Aircraft Spruce has them, I think they are a Slick part.

Grommets

Spruce pn M2375. $23.95 a pair. There are cheaper ones available but I like these.

Thanks. It looks like the cheaper ones fit the Vans specified hole geometry.
