i just wanted to ask if there was a o2 sensor tool avalible. if not what would be the easiest way to remove and replace the sensors?

 

Just about any auto parts store should have an "O2 sensor tool"... basically nothing more than a deep well socket with a slot cut in the side of it so it can fit over the wire. Problem is, its very hard to fit the socket on the sensors in the stock LT1 locations, and then get a ratchet on it. You end up using an open end wrench. Usually helps if the exhaust system is hot when you try and break the sensor loose.
