Yes, but I just had to find the right yoga position.

😆😆😆😆😆 , just one last tip , scan the car with a reliable scan tool after you finished the work if you haven't done so , coz in my car there was a code for the downstream O2 sensor and it didn't throw a check engine light , so don't rely on the check engine light to determine that the codes are gone .

Congrats! Did you have to buy one of those special sockets for the sensors? Did the old ones come right off, or did you need to apply a lot of penetrating oil and patience?

I bought a set from Harbor Freight that has a number of different sockets, for that and for diesel fuel injectors, etc. for $42.95. I squirted the crap out of them with WD-40, what the service manual recommends. It was a bit of a challenge getting them off, but not too hard.
