If it's a factory crossfire, any Chevy dealer and many parts from NAPA. There may be a few things available from any parts store.

What is the problem with the car? Perhaps it just needs adjusted.

Warm up the engine. Block both of the idle passages. There are special tools for this, but you can do it without them. This will create a very low idle. Check the spec for base or minimum idle. Now locate the small port on the top of the throttle bodies. Connect a manometer to them. Adjust the idle to have the correct speed by adjusting the base idle screws (throttle stop screws) while maintaining an equal balance between the two units on the manometer.
That balances the system. Unplug the idle passages.

If you still have idle problems, check the plugs. In a stock engine use A/C Delco plugs. Other brands will make the car idle rough with that system.
