I have a brand new, still in the package ignition lock cylinder for a steering column mounted ignition for a 1998 - 2002 GM vehicle. You can google the part number to make sure it fits your vehicle. The part number is REPC503904. They are easy to change. I bought it and the ignition started working again and not sticking so I never changed it and ended up selling the truck and bought a new one. I paid $30 for it and will sell it for $20. If your ignition sticks when turn the key trying to start it all you need is this new replacement and it'll be like new.
