Need a couple of measurements please

[Thealien]

I need to know the size of the antennae hole where the antennae wire passes into the cab.

What size are the rocker plug holes?

I need to get a couple of blind plugs for the holes and want to have them before I start taking things apart.

I was unable to get the hard rocker plugs installed so I am going to use a rubber blind plug but need to know what size they are. Can't really get in there to get a good measurement.

Thanks
Mark
