Thanks Graham, I checked out John's Rod & Custom Supplies at http://www.users.bigpond.com/hotrods.kustoms/catalogue/index.html but unfortunately amongst all the stuff they've got, there's no sign of venties.  (Sorry no pic yet Slim).  I will give them a call though, thanks for the tip.  The FC at the Nats that had the venties was a two-tone green one, (same colour scheme as mine, but heavily modified), think it was Les? from your NSW club.
Cheers, Tim.

G'day Holden Gurus

At the 9th FE-FC Nats in Qld, I spotted an accessory that I hadn't seen before...  "VENTIES" a plastic, half-moon shaped shield that fitted over the corner of the quarter vents.  I love them and I want some...  and as long as I'm dreaming, I'll take them in green.  The owner said I might get them thru either the Vic or NSW clubs, but neither Richard or Tony knew of anyone providing after market productions.  Does anyone know where I might find some?  

Cheers, Tim.
