The u-joints were both worn out in my MK1s so this is the first functional example of an early u-joint I have come across. It has a grease fitting that is accessible through the fishmouth.

Here is the patent drawing showing the u-joint.

My collection of junk early u-joints. 2 came from my MK1s. Not sure how I got 2 more. None have provision for a grease fitting.
