GM uses bolts with serrations under the heads to prevent them from spinning. You have to remove the nuts then tap the bolts out. If you reinstall the nuts backward a few threads and pound on them, you won't damage the threads on the bolt.
Most GM struts do not have slotted holes. Replacement struts often have one lower hole slotted to allow for adjustment during an alignment. Either way, when you install the lower bolts, try to position the wheel as straight up and down as possible so you can stand to drive it to the alignment shop.
