OK, welded the new balls into the wiper arm assembly. Then fitted the new nylon sockets with the metal caps that came with the kit.
In the process, I had a few issues crop up.
Firstly, the new caps, which I believe are chrome plated, lost the plating when folding the 'fingers' to secure the nylon sockets in place. Zinc plating might be more appropriate.
Secondly, the caps, although probably copied from originals, could be improved by making these 'fingers' marginally longer. (maybe only 1 - 2mm)
Thirdly, and more importantly, the nylon sockets & the new balls are not a good fit together. I would suggest that the ball to socket fitment has in the range of 0.5 - 1.0mm 'play' when assembled. Once all fitted back into the car, the end result of 'play' in the actual wiper arms, is in the range of 40mm at the end of the wiper blade.
The wiper pivots in the car have virtually no play at all & don't contribute to this problem of 'play' in the assembly.
I would consider a 'snug' fit of the ball & socket with virtually no play be far more appropriate.
By the end of the job, I achieved nothing when compared to the 46 year old worn units that I replaced.
I believe bigger balls or smaller sockets are required to solve this issue, along with a rethink of the cap design & plating.
Your thoughts Les?
I have mentioned this to Bob P after fitting the kit but have not heard back.
