it is square....Make sure you don't get the LS2 ones. and you need 24" extensions too.

is there a way to know which ends to get - flat or square, w/o having to unplug them

It is cake to get to them. They are most likely next to the transmission. They are the square ones 99% of the time on F-bodys.

you should consider just forgetting about the extensions and just buying some rear O2's from a vette. they are plenty long to use by themselves without any extensions. In my case and a few others the stock O2's won't run hot enough and will throw a code and cause your car to run shitty. The vette O2's are made to run hotter and they solved all of my problems. If you run a search you can see other peoples experiences with this.

Just something to consider. I ended up going through 2 sets of O2 sensors before figuring this out $$$$$$
