Guys, where's my Zerk fitting?

Gentlemen: I just installed a new front end kit in my very stock 1974 Duster (225 engine). It is a completely stock rebuild. I went to grease the Zerk fittings, and I noticed that the new lower ball joints don't have a grease fitting. How can this be? All the other front end components have grease fittings, but the lower ball joints don't ( see photos of the old ball joint, and the new one). How can this thing work properly if it isn't lubricated? Any ideas out there? Thanks - cruiser

It amazes me that you did not notice that before you put them in?
