installed zerks in A arms

after checking the pivot bearings on my A arms and finding that
they were wasted with rust simply because theres no way to grease them, i decided to put in grease zerks .

drilled and taped the hole and but in the zerk then ground off the
part of the zerk that sticks inside of the tube ,with a die grinder.
i then had to make a hole in the bearing that would center on the zerk .
i wanted to drill a small hole but that metal is very hard so i ground a hole with a dermal disk mounted in the drill press

realizing that perfectly lining up the hole with the zerk could be a little difficult i improved my odds by cutting a cross groove
