I got boneyard spheres from another 300TE. That was hard enough. Got the passenger side done on mine, which eliminated the bunny hop from neither rear wheel having shock action. But the driver side, which should be the easy one, the allen head bolt that goes into the sphere rounded out. Tried heat, various tools, easy outs, gave up and drove it with one side better. It is a royal PITA job on ramps under the shade tree. Be sure to wash out the allen head bolts with brake cleaner, so tool will go all the way to the bottom.
