Go to any auto parts store and they should have them for a few bucks. Then go to sears and pick up the correct drill bit and tap for the zerks. Now the sucky part. Your more than likely going to have to remove the upper A arms and the bushings and drill and tap the arm for the zerk. You can do this yourself or have a friend do it. Use lots of oil when drilling and tapping as it makes life so much easier. Then regrease everything install and if it squeaks give it a few shots of grease and all should be well. Also if you search you should be able to find pictures of where to install the fittings on the a arms.
