S10 Xtremes do NOT have disks from the factory, but 2wd Blazer Xtremes do. The 4wd rear is 2.5" too wide for your 2wd truck. Also, if you get all the disk brake parts, you can swap it onto your existing axle without much effort, you will need to open the cover and yank the axles out, not a big deal.
