I spent the weekend fitting the chrome wing trims, it was a steep learning curve.  I  had several different approaches and eventually hit on the winning formula of having the tabs long and using a screwdriver to lever them in.  I have almost finished but the back driver side wing needs some more TLC which needed the wheel to come off and I need to take the car out of the garage to do that  however, it has started to rain in London so it will be another day.

I then fitted the wing trims which was easy and pleasing on the eye.
