No. Campagnolo still sells G-springs and carriers for 1998-2008 ergo levers. You can even buy them from Amazon.
Stock up in case Campagnolo discontinues them as they did with 1992-1997 and 2009+ shifter small parts.
or have these remained essentially the same in the intervening time, thereby allowing me to use new stock?
Fortunately, Campagnolo replaced the G-spring mechanism with Ultra Shift in 2009 which has ball bearings engaging the shift detents with separate coil springs behind them. My 2010 Centaur Carbon levers made it 24,000 miles before requiring service, which is 3X the time it took for my G-springs to fail because they abraded or broke from fatigue. The front paddle return spring broke, although that part is similar to the one used in the older shifters which fail the same way.
If you want to do that, you'll want 2010 10-speed levers (the 2009 model year had soft detents); or 2014 (the levers changed in 2015) 11-speed Ultra Shift levers with a 10-speed index cam + front ratchet from crashed levers or EC-CE100 10 speed lever body (you can get then for $70).
OTOH, the move to the 90 degree cable guide in the shifter body cut rear shift cable life in half and I'm now on a 2000 mile cable replacement interval (4000 for housing). Pick your poison.
