Hello Jim, I don't know where you are located but Juergen of s-parts.de frequently advertises Heuer re-edition and TAG-Heuer parts on the Chronotrader section - which is btw where you should also post a WTB ;-).
For example:

Recently he's been selling Monaco glasses, so Carrera's could be in stock as well.
I've had business with him in the past and he's a very nice and reliable seller - and seems able to ship worldwide.
Hope this can help.
