Dont remember sizes, but combo wrenches, deep well sockets, vise grips, spray lube and possibly a hacksaw or cutting torch. A lot easier with both wheels off the ground. Dont let list scare you. A lot easier than it sounds. Hacksaw and torch might be remotely needed in an extreme case. Pb blaster would be my rust-buster of choice.
i replaced mine a few years ago. one set i had like the originals were threaded at both ends, a major pain. i got a set that were actually like a long bolt so you only had to worry about one end, the threaded end goes up. a torch and pb blast helps with the nuts but there is a good amount of tension. if you have a compressor with a cutting wheel that would also work. make sure you wear safety glasses. when i put the new ones in while the car was jacked up if i remember right i used a scissor jack to help push from under the bar to make it easier. if there is too much space you can put the jack on top of a 2 x 4 or something similar.
