No.
And does anyone have a source for 8s Ergo parts?
No apart from G springs and left spring carrier which are common to second generation units. Campagnolo discontinued the first generation small parts a few years ago - I bought Branford Bike's last two right carriers sometime between August 2010 and May, 2011 and Loose Screw's last right paddle return spring in May, 2011.
They also discontinued third generation small parts in 2009, preferring to sell complete shift assemblies for ~$90 a side including everything but hood, brake blade, and mounting hardware.
Stocking up on right shifter parts would be prudent in case they get rid of those too - lots of G springs and carriers which are the main wear parts, plus a paddle return spring, thumb button return spring, and paddle assembly.
Over 15 years I had one return spring and ratchet spring in the paddle assembly crack due to fatigue.
I replaced thumb button springs at least once, but may have bent one on installation.
