NIGGLY TRIM (Commodore VZ Wagon) replacement clip needed

Hi all,

My VZ Commodore wagonwheels has a niggly trim problem, right side rear passenger seat pillar (see photo). On the left hand side of the rear seat, this "intersection" of mouldings is rock solid — no issue. But the right side, as per the picture, is missing a peculiar type of clip to bring the two mouldings together firmly.

I have been unsuccessful in trying to find out what sort of trim clip is needed for this repair. Does anybody here in the trim industry know what I require, or if there is a business in Geelong or Melbourne that can repatriate this singular, one and only annoying thing of a much-loved go-kart? I have tried using araldite, but it did not stick (!) Instead, it stuck to my fingers!! :help:

Thanx!
