yes, to reach inside carpet is hard, if you have small hand is easier but is do-able, just take your time.
my suggestion is remove BOTH front wheels for two upper sensors, more room for you.

Maybe I just got lucky but I just finished up both front o2 sensors in about an hour. Prying the heat shield a bit away from the connector was all I needed to get a pick in there.

Bu comparison the front o2 sensors of my rusty ranger were a thousand times more difficult. If you have a clean LS and the sensors arenít seized in the manifold, Iíd put this at about a 4 out of 10 on the difficulty scale.
