I acquired my first Morgan, a 1971 4/4 4 Seater, in 1976 which I adored and rebuilt. It came with the one shot oil system but after I got through one set of king pins I decided to change to grease nipples. Worked a treat and my second set of king pins lasted until I sold the car in 1981 with over 80k miles on the clock. In short, fit grease nipples.
