I have a 2000 Chevy extended cab work truck package with the cloth manual seat. It is set up with the two buckets and solid center seat without the armrest. I need to find a new drivers seat and would like to know what seats are interchangeable with my truck. I would think the Sierra is the same seat but any suggestions are welcome. I am planning on going to a pick-n-pull type junkyard to find a new used seat and want to expand my GM model options if possible. I was looking at my current seat and it appears to have the star/torx type nut on the rail. Does anyone know the size/description? I will have to get the special type of socket so I can pull the seat. Love those GM fasteners. Thanks for any suggestions
