I am getting ready to replace my front crankshaft seal and sensor on my 2007 Grand Prix supercharged series III. Does anyone know if there is a balancer repair sleeve for this model? I searched and did not find much on this. I want to have one on hand just in case there is a groove on the balancer when I get it off. Also any tips or videos on how to install the sleeve if there is one. Any help is appreciated.

Thanks
