Main bonnet centre support bush

[Speed 3]

On the main bonnet there is a solid rubber "foot" on a threaded spindle that supports the rear centre of it. On mine, the original is perished and means the bonnet sags and sits on the passenger side wiper arm. I have packed it out with self adhesive furniture floor protectors but it keeps collapsing over time. This foot doesn't seem to be procurable from any of the normal parts suppliers and I'm struggling to describe it in a google search. Closest I can get is solid rubber or nitrile cord which seems to to up to 40mm dia but its only sold by the metre and that seems a bit of overkill when I only need 20mm or so. Anyone got any ideas or had a similar problem ?
