You will have the standard Morgan Sliding pillar front suspension on the front of the car. You can see a picture of the components at
http://www.gomog.com/allmorgan/sus.html The wheel is mounted to the stub axle and the stub axle rides up and down along the king pin. There are two bushes in the stub axle. These bushes are made of varying materials. Not sure what you would have. The king pin goes inside the upper main spring and the stub axle is located between the upper and lower springs. There is a shock absorber there in parallel to the springs to reduce the oscillation.
The best way to find all the grease nipples is from below the car.
