I am thinking about going from stage 2, to a 2.9in pulley, but I don't have the tools from the gm stage 2 kit. Is it possible to remove it without the special bit, or do i have to order the parts from GM if thats even possible..

 

I used a pair of Vice Grips on one car.,.. worked fine. just pad it a little. I think it was RedlineBrians actually

 

bolt extractor.. thats what i had to use
