Go to your local wrecking yard and look for one. You can try gmpartsdirect.com as they may be able to help you too. The vacuum lines should be relatively inexpensive to replace as these can be purchased at any autoparts store. You may also want to clean the Idle air control motor. (IAC) This will help the idle somewhat although if you have bad vacuum lines things will improve greatly once they are replaced.
