Sway bar Question

[Ewr101]

I have a 72 Blazer 2 wheel drive with factory coil springs all around and trailing arms in the rear. In the process of looking at the body bushings I was going to look at the sway bar bushings as well to see if they needed replacing. I saw no sway bars in the front or the rear.

Did Blazers not come with them from the factory? I don't know much about all the little options and other particulars concerning the suspension so any and all details would be greatly appreciated. Thank you.
