Ignition switch barrel replacement

[Gray]

Any tips on how to replace the barrel on my mk1 ignition switch, I pressed the plunger in through the small hole on the side to extract it but you cannot depress it to relace it, this makes the plunger foul the inside of the switch body before it sits fully home.

Ok, worked it out, when I shone the torch down it after cleaning I could see it is ramped so just push a tad harder

I never have problems where brute force & ignorance is needed

Its finesse that I lack!
