Sway bar mounting question

[bigcarguy]

I went to the junk yard and picked up a swap bar and the mounting brackets. I had to get one of the guys out there to use his air tools to get the brackets off because they weren't bolted on, the just had like a mushroom head on both ends(forgive my ignorance of their real name). I didn't think much of it until I looked at my truck and noticed that the crossmember also uses one of those mushroom bold things right where I need to put the bracket. How can I take those off at home with no air tools? Also, what do I use to put the brackets on my truck? Can I just bolt them on here or do I need to do more?
