As already suggested a grease nipple will be useful, but originally the threaded plug you have was standard, see http://archive.a7ca.org/wp-content/uploads/PL_888B.pdf Greasing was done by temporary fitting of a grease nipple, I believe. Also the two bolts through the sides of the housing locate the castellated adjustment ring; by removing the bolts you can take up the play if any. Also the ball joint at the anchorage should be adjusted to eliminate play, and well greased. Do not make these adjustments too tight; particularly after tightening the ring take it back to the next location where the bolts can be replaced. Other ponts to examine are the rear universal; it can get a bit noisy if wear is excessive. Also the fabric coupling at the front needs to be in good condition. If the car has not been subject to regular maintenance in your hands examination of all the transmission adjustments and correction of any major play will give improvement.
