Greenmorgan,
Have a look at the link below. However your Kingpins may not be compatible with Grease as a lubricant. This has been highlighted by some of our US brethren as they say that the grease will not exit the kingpin in the region of the top bushing. I would advise consulting one of the Morgan dealers that advertise in Miscellany
