Does your 4/4 just have nipples a the bottom of the springs? (Mine does, and is the same age)
In which case you may wish to consider the following: It is possible to over-grease at that point, in which case you risk grease coming up from the greasing point, through the spring coils and going onto the brake discs.
By crawling under the car with the grease gun, you can check on this each time you greaee.. . . . . just a thought.
