Hi Tony
Though this source is a little far away from you, OK its the other side of the world,
http://macsautoparts.com/search.asp?...ndle&x=11&y=15 but thought it might be interesting. There are some very close matches to what I've seen on both Ford and Chevy Pat 11 & 12.
Only problem is all this stuff is chromed.
Please let us know what resources for reproductions you turn up in Oz.
Cheers Phil
