Whilst not strictly in the parts book, it came into use on FE and FC vehicles

Is it a Valve Stem seal.

You're on the right track, tell me why these are used and not on FB or EK for instance ::)

The early rims had a larger hole
because there on a bench top and not in the car? :P
FE & early FC had the larger valve stem hole in the wheels for tubeless tyres which I believe were
fitted from new
The early tubeless valve stems were wider at the base than the ones we use today
When fitting tubes these doo hickey's were required to centre the valve stem within the larger hole
As the early wheel centres were only riveted to the rims, tubeless tyres were sometimes prone to leaking air
from the rivet holes
Later on the rivets were replaced with spot welds
Up until a few years ago you could still hunt down the wider tubeless valve stems, not sure if they are still available these days
From memory I'm sure I've seen a bulletin stating that Holden went to tubeless tyres sometime in 1955, during FJ production???

Hi gp.
My service bulletins state Jan 1956 for tubeless tyre intro.

Zulu, I couldn't have said it better. I'm pretty sure the larger tubeless stems are still available. I had them fitted on the 3 tone sedan but that was a little while ago I guess. :'(
