Well that's good. I've yet to be so lucky or anyone I really know on these. I'm not sure how big the engine compartment is in the Le Savre but in the Pontiac Grand Prix (ive done before and had friends with them) there is not a hole lot of room left. I'm sure that there's a place you can cram your hand in but it's not ideal or how Chevy has it being listed for changing.
