Look what Firebird Central has in stock now:

Never before available for 1969 Firebirds. Pretty cool. Not close to being exact printing style, but I wonder if you can reuse your original recessed white printed cover on this part... if someone buys this part let us all know.
Used ones that are subject to fail go for like $95 (although I just missed out on an NOS one for around that price on ebay) so this is not bad to have a switch that will actually work.
