Ignition coil repair kit.
 

Howdy.
Has anyone tried to purchase a repair kit for our beloved Lucas ignition coil pack?
I found this one on Aliexpress: https://www.aliexpress.com/item/Igni...834835544.html

One of my coil packs has exactly the problem that could be solved with this thingy - the bottom part that is being put on the spark plug is cracked. For a quick fix i`ve taped it with an isolation tape and it works, but it is not a long term solution. Want to know, if this replacement part is any good or just money (more precisely - time) waste?

If nobody has tried it, i`ll order one piece for myself and then let you all know if it`s worth it.

Its just a rubber boot and an aluminium spring loaded pin, these are fine to use and are much better than 20 year old boots which are very hard and will crack easily if you try to remove them.
I have plenty of these here from all the crappy chinese coils that only last a year. I bin the coil but always keep the rubber boot.
