Door to A pillar rubber grommet/hose, small bumper

I saw a post from 2016 about the rubber hose for the wiring between the doors.

Mine is the small bumper and is not the bellows type but a straight rubber hose between the grommets in the A pillar and door.

Can can anyone tell me what rubber hose to use, internal and external diameter? TIA

It isn't a hose it is a bellows.

Thanks you. I have the bellows on order but the 2016 post with photo looks the same as mine and appears to be a piece of hose between the grommets. She is in for some paint at the moment will wait and see they fits I know the bellows were fitted to later models so hopefully will work.

Mine is a 1984 cabby and that also has a smooth hose rather than the 'bellows' type.
