Ignition wire/distributor cap issue

My Mk1 cabby has developed an issue recently where, during hard revs (such as overtaking), the ignition leads are popping off the distributor cap. Pretty minor but it is driving me a bit mad!

Anyone got a solution to this (other than not overtaking!), or any way to secure them? I don't really want to go changing the cap & wires as I think they're less than a year old.

sounds like you have a missmatch between the leads and cap, or they're just cheap garbage.

new bosch/beru make ones are cheap so id just bin the lot and start again:

im assuming its a standard 8v right? are the engine mounts ok, wondering if they're loose and engine is flappign about too much…
