Good afternoon guys....
I worked at the main Crewe factory in Aftersales for over 20 years as their main Technical Author so might be able to help a few out with any remove and fit questions.

Anyway, here's the template drawing that you'll need to fit the larger and oh so much better Bentley wings & boot release badge to the earlier cars that had the awful microswitch assy.

I have also added the apertures of the old and new boot, plus the procedure to fit it.
