1. The strut to clevis (fork) bolt doesn't have a separate nut, the clevis is threaded on one side for the bolt.
2. This is mostly for the bolts going through a bushing, but won't hurt for the rest. I found it was easier to do with some long extensions (especially for the clevis to control arm bolt)
3. see the pictures attached, top is for the front, bottom is for the rear, from the Factory Service Manual
