the Heater Delete option?

Cool stories...
I acctually put an add in for the block off plates in a Facebook group over in Australia but no luck so far.
As for pics of the vent box thanks, but I have gathered some 30-40 over the years, from all angeles, so I´m well prepared once I deside to go.
And door is 4 1/4" X 6 3/16" witch is slighty smaller than driver side door.
Ha, that's funny about the FB group ad, probably your best shot these days.

Unfortunately though, you're probably coming up empty because as far as I know, '67-'69 Barracudas were never produced down in Australia, only Valiants. Chrysler Australia was a low budget operation and it's highly doubtful that any Valiants would have come equipped with a left-hand drive, USA Rallye style dash.

Maybe try Jim Kramer in PA. Jim has an original B029 so he would at least know what you're looking for.

Thanks for the info on the door dimensions. I'm not sure I ever put my right and left side boxes next to each other for comparison.
